Currently, a flash drive is a common and necessary device for storing information. Even a novice PC user can easily write or delete data from a flash drive. But since this equipment works in conjunction with complex computer technology, there are situations when information cannot be saved or erased. And the question arises, what to do if files are not deleted from the flash drive or, conversely, it is not possible to restore them.
How to clean the drive if applications and documents are not deleted.
How to format USB
You should know that when you delete information from a drive, it is not the file itself that is erased, but only the record about it. For example, like in a library, a book is lost, but a card stating that it is there remains. And therefore, knowing how to delete everything from a flash drive, you can either restore the information or completely get rid of it.
- Simple deletion of information by right-clicking on a folder or group of files and selecting the “Delete” line.
- Complex deletion using the Shift+Delete keys. This combination deletes data without throwing it in the trash.
- Complete flash formatting in “My Computer”, where when you right-click on the USB drive in the window that opens, select the “Format” line and click “Start”.
- Software removal using CCleaner. This utility is completely free and can be downloaded from the official website. In the program window that opens, select the “Service” tab, “Erase disks”, where check the box next to “flash” and click “Erase”.
IMPORTANT. All formatted data in these ways can be easily accessed by typing “Recover deleted file” in the search bar.
Method 3: Formatting
If the previous method turned out to be ineffective, you should move on to more radical solutions, the first of which is completely formatting the memory device.
Important! This process will delete all the contents of the card, so be sure to copy all important data from it!
In the next window, uncheck the “Quick (cleaning table of contents)” option; do not touch the other settings. Click “Start” and wait for the procedure to complete.
Tap on the three dots to open a menu where you can use the “Storage Settings” item.
Click "Format" and confirm the operation.
Typically, erasing the information from the card helps resolve the problem.
Possible solutions to the problem
When you enter the question “I can’t delete a folder from a flash drive” into a search engine, the browser usually produces a bunch of information from which you have to select the appropriate problem and solve it. In fact, this is not very difficult to do even for a beginner.
If files from a flash drive are not deleted, what to do with hardware protection
Modern drives have a special lock on the device case. It is he who enables or disables the blocking. It is enough to switch it, and you will be able to save or remove information from the media.
If a folder is not deleted from a flash drive, what to do with software protection?
For an experienced programmer, there are many options for how to remove non-deletable files with software lock from a flash drive, but the average person can try simpler methods:
- Formatting. If there is no valuable information on the drive, then you can do this with the right mouse button and in the options set the file system (NTFS) and the cluster unit size (4096 bytes).
- Removing the virus. If the system perceives a removable disk as a virus and blocks the entire process of working with it, you should check the USB with any antivirus and, if possible, destroy it.
IMPORTANT. If after all the manipulations there is an empty folder left on the USB, you need to restart the PC and delete it again.
How to delete all data from a flash drive if it is being used by another process
This is a fairly common problem and you just need to close this mysterious program if it is known or use a third-party utility (Unlocker, LockHunter, Iobit Unlocker, etc.). Unlocker is one of the best programs to remove undeletable files.
- It integrates independently and quickly into the system.
- Right-click to select the USB drive and click on the line “Unlocker”, “Delete process”.
- If the program cannot perform an action immediately, it will offer to do so the next time the system boots.
- When you “Unlock” a file, it will become free, making it easy to delete.
IMPORTANT. All of the listed applications have a huge disadvantage; they will not be able to warn you about the erroneous deletion of system files.
Presence of errors
It may be that the disk is damaged or the contents are not recorded correctly, then the system generates an error. In this case, you can eliminate it. In the root USB folder, right-click “Properties”, “Tools”, “Check for errors”.
When formatting a flash drive, you need to understand that there can be many usual ways to delete information, but in the case of non-deletable data, the Unlocker file manager can be a good assistant.
Hardware protection
On new flash drives, to remove write protection, sometimes it is enough just to change the position of a special lock installed on the case. It is he who completely disables/enables write blocking. So inspect your device, if it has such a switch, slide it in the opposite direction and try again to move the necessary folders from the computer.
Why are files not deleted from a flash drive, SD card, or Windows computer?
As mentioned earlier, the inability to delete a file from a computer may be due to a number of reasons:
- At the time of deletion, the file is being used by some program or process;
- The file is used by a network user;
- The user does not have the rights to perform this action;
- The disk on which the file is located is write-protected;
- The file is damaged or infected with a virus;
Obviously, before taking drastic measures, you need to close all programs and processes that may be using the file, make sure that the file is not open in any computer accounts, and that you have the administrator rights necessary to delete the file. You also need to check your computer for viruses.
In addition, there are special switches on the bodies of removable media such as USB flash drives and SD cards that block the possibility of any changes to the information on them. If you are trying to delete a file from a flash drive or SD card, then try moving the switch to a different position and try deleting the file. If this doesn't help, move on to the next section of our article.
Image 2. Location of the blocker on flash drives and SD cards.
Method 1: Disabling write prohibition mode
Many SD memory cards (and corresponding adapters for smaller cards) have a hardware overwrite mode, which is implemented in the form of a lever on the device body.
If the switch is in the “Lock” position, this means that the data on the media cannot be edited, including deleted. So the first step is to turn off this function by moving the lever to the upper position. If the drive still reports that it is in write protect mode, proceed to Method 5.

Software protection
With software blocking the situation is a little more complicated. You will need to perform some manipulations with system options and directly with the protected flash drive. The focus of the effort will depend on the shutdown method used. Let's consider separately how to perform them correctly.
Note. If the guide you choose fails to remove the write blocking, try using another one. The effectiveness of the “recipe” depends on the specifics of the defense mechanisms.
Method #1: Unlock using formatting
If you don't have valuable information on your drive, do the following:
Advice! If you don’t know how to quickly clear a flash drive of all data, or files from the flash drive are not deleted (selectively), also use the formatting function.
Method #2: eliminating viruses
Some computer malware mischiefs in a special way. Having infected a flash drive, they make sure that nothing is deleted on it and nothing is written to it. That is, they completely block access. Therefore, before plunging into the jungle of Windows settings and going into painful research like “why it is impossible to delete and write,” check the USB drive with an antivirus and, if necessary, destroy the blocking viruses found.
Method #3: Disabling the ban in Windows
Prohibiting writing to an external drive can be enabled directly in Windows. Check the status of this add-on. If enabled, disable:
2. In the “Run” panel, type - gpedit.msc, click “OK”.
3. In the Local Group Policy Editor, in the “Computer Configuration” section, open: Administrative Templates → System.
4. Click on the “Removable Storage Device Access” folder. In the adjacent block, double-click on the “Removable disks” option. Deny recording."
5. Click the Disable radio button, then Apply and OK.
Note. If this add-on has been disabled, it means that the recording is blocked for another reason. Follow method #4 or #5.
Method #4: Unlock via command line
1. Click the Start button. Type cmd in the “Search” line.
2. Right-click on the icon of the same name that appears at the top of the panel.
3. In the list of functions, click “Run as administrator”.
4. In the command line console, enter the directive - diskpart. Press "Enter".
5. In the utility line, type - list disk and press “Enter” again.
6. In the list of connected drives, find the flash drive (it’s easy to find by size; see the “Size” column). Remember its serial number (for example, Disk 2).
7. Execute the following list of commands (enter them in the line, and then press “Enter”):
Wait for the operation to disable the protection to complete (the progress is displayed in the line ... percent completed).
Method #5: registering the key in the registry
1. In the Start window, type - regedit. Click on the editor icon.
HKEY_LOCAL_MACHINE → SYSTEM → CurrentControlSet → Control
3. If there is no “StorageDevicePolicies” section in the “Conrol” branch, create it:
4. In the StorageDevicePolicies branch, create an entry:
5. Set the value in the created key to 0 (click twice on the entry, enter the number in the “Value” column, click “OK”).
6. Reboot your operating system. Connect the flash drive.
Method #6: unlocking with special utilities
If you are not computer savvy or prefer automated methods of changing settings, then it is better to use the services of special assistant programs. Here are some solutions that have proven themselves in practice:
JetFlash Recovery Tool - the utility removes write protection on Transcend, JetFlash, A-Data flash drives (only on them!). After launch, it detects the media and corrects the problem. To download the Recovery Tool, go to the brand’s website - https://ru.transcend-info.com/. Type Recovery in the search bar. In the search results, click the JetFlash Online Recovery link.
Apacer Repair V2.9.1.1 is a powerful tool. Helps users out when the lock cannot be removed using standard means. The utility supports removable media from Apacer.
Good luck unlocking your flash drive!

How to delete a file or folder that cannot be deleted via a computer?
Method 1: Just restart your computer, in most cases this will be enough.
Method 2: Enable Task Manager. Press Ctrl + Alt + Delete if you have Windows 7 or XP and Windows + X if you have Windows 8. A window will appear in front of you, go to “processes”.
All programs that are currently running on your computer will be displayed here. Try to find exactly the one that might use your file. If it doesn’t work, then just select any one at random and click “end process” each time trying to delete the file again.
Method 3: Turn off your computer and turn it on again. During the boot process, press the F8 key many times. A black screen will appear in front of you, where there will be several options to boot your PC. Select "safe mode". As soon as the computer boots, try to delete the file or at least move it to another location.
Method 4. If the file is simply not deleted, but can be transferred, then you can proceed as follows. Just drag your file onto an empty flash drive and format it. Be careful, after this process everything will be deleted from it!
Method 5. Open your computer and find your non-deletable file on the desktop. At the top of the window, click “service”, then “folder options”, go to the “view” tab and uncheck the box if it is next to “use simple file sharing” and save the changes. Try deleting your file or folder.
Method 6: Change administrator rights. Right-click on our file, select “property”, then in the window that opens “security” and click “advanced”.
Another window will appear, click on “owner”. Here simply select another administrator and click “apply”. Personally, this operation helped me remove restrictions from my WordPress templates, which I wrote about.
Method 7: Disable all processes associated with this file. This procedure is very similar to the task manager, but it has a more effective effect. Click "Start" on your desktop, then "Run." In the window that appears, enter msconfig and press OK.
Another window will appear in front of you. Here go to the “startup” tab and in the list of running processes try to find the name of your non-deletable file and uncheck it, and click ok.
Method 1: Change disk properties
The main software cause of the problem in question is the restriction of access to data in the disk properties. This can only be eliminated using a Windows computer, the sequence of actions is as follows:
Note. For this feature to work, your account must have administrator rights!

Reconnect the card to the computer and try to delete unwanted files - now the operation should complete successfully.
How to delete files and folders that cannot be deleted using special programs?
Method 8. To solve this problem, a very cool and at the same time simple program “UnLocker” was created a long time ago, which is capable of deleting files that cannot be deleted in 90% of cases. You can download the program from the official website. During the installation process, be careful and uncheck the box where you are offered to install another application in addition to the program. If you don’t do this, then at the end of the installation your antivirus program will swear for a long time.
Ok, now just right click on your file and select “UnLocker”. A window will appear in front of you where all processes that use this file will be displayed. Select it and click on “unblock”, then “delete”.
Method 9. In addition to this program, there is another one called “IObit Unlocker”. You can download it. This software works similarly to the first one. Simply click on your file, select the “IObit Unlocker” tab and delete it.
Method 10. If none of the methods listed above helped you, then you can try your luck with other programs. There are a whole bunch of them on the Internet. Here are just the ones that I know: TotalCommander, DeleteDoctor, FileASSASSIN, LockHunter, FreeFile Unlocker.
That's all, good luck!
Method 5: Card recovery
The worst case is that due to a power failure, the card controller switched to read-only mode, which is not very easy to remove. However, software from the manufacturer can help solve this problem: most of these applications implement the function of resetting the microcircuit to the factory value. Software from flash drives is also suitable for memory cards, so the manuals are also relevant for them.
But sometimes even such programs are powerless. This means that the device can only be restored to functionality using specialized equipment. If this is important to you, contact a service center, otherwise just purchase a new drive.

Using Unlocker
The simplest and most popular program, but now even on the official website a warning about unwanted software is displayed. Along with the program there may be some other virus or advertising, so use at your own peril and risk. Try the methods above first. Website: https://www.emptyloop.com/unlocker/.
After installation, a new item will appear in the context menu, which is called Unlocker. After clicking the button, the program will complete the interfering process and the file will be unlocked.
If you want to delete a folder, first delete all its contents.
Vaccination of flash drives
A flash drive vaccine is a kind of software protection in the form of a special file (Autorun.inf). It prevents the virus from “settling” on the flash drive: it blocks its functions. Used exclusively as a prophylactic and warning agent on “healthy” USB drives. It is created manually and using special programs. We will get to know some of them better.
Panda USB Vaccine
A utility from the famous antivirus company Panda. Has a volume of less than 1MB. However, very useful. Available free of charge on the official website. After launching USB Vaccine for the first time, in the panel, check the boxes next to “Hide tray icon...” and “Enable NTFS...”. And then click “Next”. Connect the USB flash drive and click the “Vaccinate USB” button in the application window.
Autostop
Does not require installation. Runs in the MS-DOS console. At the request of the user, he can not only “vaccinate” the flash drive, but also disable autorun by changing the registry settings, and prohibit writing data on the media.
USB Defender
An efficient GUI tool. Activates USB storage protection in one click (and disables it in the same way). Carefully hides the presence of the “grafting” AUTORUN.INF on the flash drive.
Let your USB drives avoid viruses!
Go to “My Computer”, then to removable media.
Select all files with the left mouse button or press ctrl+A.
Click "Delete" on . The PC didn't actually erase your files, but marked them for itself as . It looks empty, but the files can be restored using a special program.
Quick formatting will also lead to the result described in the first case, which can be done this way:
go to “My Computer”.
Right-click on the flash drive image.
In the menu that appears, select “format”.
Check the box next to "Fast".
Click "Get Started."
The program will ask: “Attention, all data will be deleted, continue formatting?” Click Yes
Click Yes.
To deeply clean the flash drive, select the “Full” mode in the formatting program. All other steps are the same as quick formatting.
This method will delete all files, but their recovery will still be possible in a specialized service center.
If you need to delete the contents of a removable drive without the possibility of recovery even by specialists, use a special flash drive cleaning program or, after completely formatting, fill its entire volume with extraneous files, for example, music, and then format it again.
Experienced users of personal computers may not have any problems with deleting information from a flash drive, but for beginners this may be an insurmountable obstacle.
Causes
A flash drive can be blocked for many reasons. The most common ones are listed here:
- Incorrect Windows settings, for example, a software ban installed in the operating system;
Failure of the media, often poorly produced “flash drives” - Chinese counterfeits of world leaders; The physical switch is in the wrong position; The host is infected with a virus; Malfunction of computer USB ports; Lack of a driver responsible for correct device recognition; Incorrect use. For example, you cannot remove the media until the process is completed: writing, downloading, renaming, moving or reading;
These are not all the reasons that cause the consequences of the write protection of the media being triggered. But if you still encounter a similar error, this does not mean that you need to change the flash drive.
Audio Comparer Overview
This utility belongs to a rare category of programs - searching for similar audio tracks, not by size, entered tags or file name, but by the direct content (sound) of the audio sequence. Scanning audio tracks takes some time, but thanks to this, high efficiency is achieved in searching and identifying both complete copies of audio files and very similar sounding ones, which are located in different folders on your personal computer.
When you launch the program, a wizard window will open in which you will need to specify the scan folder(s) and select what you want to find: complete copies or similar-sounding ones. At the last stage of the wizard window, you will need to specify the file name and path for the report file. This file may be useful if you need to visually see scan results in the future.
If you have a very large collection, it is recommended to first scan between a small group of audio files in order to understand the basic principles of the program. And after that, scan your entire collection.
After specifying all audio files and other parameters, start the scanning process. If there are a lot of files to be scanned, the process will take some time. For example, 6 thousand audio tracks were scanned in an hour and a half.
When the scan is completed, a window with the results will be displayed. In it, opposite each track for which similar compositions were found, the percentage of similarity will be displayed. After listening to them (the program has a standard player for playing and evaluating similar compositions “by ear”), you can choose which copies to keep and which to delete. Everything is quite clear and convenient.
What to do with viruses?
In conclusion, it remains to consider only computer security issues related to viruses blocking access to information stored on removable devices or to the flash drives themselves.
In the simplest case, it is recommended to check using portable scanners like KVRT or Dr. Web CureIt!, and if it is impossible to neutralize threats with their help, use disk utilities with the general name Rescue Disk, which allow you to load your own environment before the operating system starts and perform a deep scan of everything that is available, including removable drives and operational memory.
Very often you can find autorun.inf files on flash drives, which can be either infected objects or components of virus programs. Removing them is not difficult even manually through the command line using the command “del \File name” (in our case del \autorun.inf) after entering the root of the media.
Introduction.
A collection of music files inevitably contains duplicates.
Some of them may be necessary (remixes, album and live versions, etc.), others just take up disk space and clutter playlists. You may decide to simply replace some MP3 files with similar files in FLAC or APE format to listen to music without loss of quality. In this case, you will have to remove duplicate MP3s. Doing this manually can be quite time consuming, so it would be a good idea to automate the process. However, most duplicate finders cannot detect that an MP3 file is a duplicate of a FLAC file. In general, deleting duplicates will free up disk space without having to delete anything you need. Here we will look at how you can remove duplicate music files using Music Duplicate Remover. This program supports the most popular audio file formats and can recognize duplicates in various formats, with or without tags, etc.
Via command line
There was such a case that the file did not want to be deleted in any way. The size was 0 bytes, the name was written in Russian letters (not supported in older versions of MS-DOS), there was a Read-only attribute and an A attribute (only reading and adding content). The command line helped.
That's all for now. If you know simpler and more effective ways, write them in the comments. Which method helped you?
Sometimes a user needs to completely delete data from a flash drive. For example, this is needed when the user is going to transfer the flash drive into the wrong hands or he needs to destroy confidential data - passwords, PIN codes, and so on.
Simply deleting or even formatting the device will not help in this case, since there are programs for data recovery. Therefore, it is necessary to use several programs that can completely delete information from a USB drive.
Let's look at ways to completely delete information from a flash drive. We will do this in three ways.
Method 1: Eraser HDD
The Eraser HDD utility completely erases information without the possibility of recovery.
Once deleted, it will be impossible to restore the data.
Method 2: Freeraser
This utility also specializes in data destruction.
Due to its reliability and ease of use, it has gained popularity among users. To use Freeraser, do this:
Method 3: CCleaner
Method 4: Delete data multiple times
If you urgently need to get rid of data on a flash drive, but there are no specialized programs at hand, you can use the manual overwriting method: to do this, you need to delete the data several times, write down any information again, and delete it again. And do this at least 3 times. This rewriting algorithm works effectively.
In addition to the listed methods of using specialized software, there are other methods. For example, for business processes you can use special devices that allow you to destroy information without subsequent recovery.
It can literally be mounted on a flash drive. If it falls into the wrong hands, the data is automatically destroyed. The Magma II system has proven itself well
. The device destroys information using a generator of ultra-frequency waves. After exposure to such a source, the information cannot be restored, but the medium itself is suitable for further use. Externally, such a system looks like a regular case that can be used to store a flash drive. Having such a case, you can rest assured that the data on the USB drive is safe.
