The USB flash drive is infected and the folder is gone

If you still have data in your MP5 that you want to save, please back it up to your computer and format it in MP5. If you can't see anything in your mp5, and there is nothing to back up, and there is a backup in your computer, then you can directly talk about mp5 formatting. External memory can also be managed by normal formatting, which can improve the operation speed of external memory.

I've looked up some relevant information, you can try it. I'm looking for you, don't worry.

Hello! Since you don't want to format it, you can plug the USB flash drive into your computer and use Tencent PC Manager to clean it. Open Tencent PC Manager, select Virus Scan, select the designated location Scan, and set the location to U disk. Hope it helps.

The USB flash drive cannot be opened, and the reason for the corruption of the displayed file or directory is:

Because the original format of the USB flash drive was NTFS or FAT, the format was changed to RAW format after power failure, resulting in a prompt of "file or directory is corrupted and unreadable" when opening the USB flash drive.

The workaround is:

1. Click the start menu in the lower left corner of the desktop. Enter the USB flash drive repair command chkdskf: f. Here the uppercase f represents the U disk name F disk, write it according to your U disk name, and then press the enter key to run.

2. After running the command, it will automatically enter the repair process. Please wait patiently for about 20 seconds.

3. When the execution is halfway through, there will be a prompt "whether to convert the missing link to a file (y n)", enter "n" and press the enter key to continue running until it is successfully terminated, and the USB flash drive will be repaired at this time.

4. At this time, the USB flash drive can be opened normally.

The solution is as follows:

First of all, solve the problem of not being able to open, start--run, enter the drive letter where the U disk is located, press enter, you can open and delete the virus next:

Tools -- Folder Options -- View -- Uncheck the box in front of Hide protected OS files and select Show All Files.

Finally solve the problem of not being able to open:

Start – Run, type cmd, press enter.

In DOS, enter chkdsk and the disk f you have problems with (e.g. d, enter chkdsk d: f) and note that there are spaces.

Press enter to start deorganizing the disk.

It is likely that the original format of the USB flash drive was NTFS or FAT, and the format was changed to RAW format after power failure, resulting in the prompt "The file or directory is corrupted and unreadable" appears when opening the USB flash drive.

1. Open the "My Computer" - "Tools" - "Folder" option in turn, remove the check box before "Use Simple File Sharing", you can right-click on the NTFS formatted disk, and the security options will be displayed in the property menu.

2. Open "Control Panel" - "Management Tools" - "Local Security Policy" - "Security Options" - "Network Access: Sharing and Security Mode of Local Accounts" after "Guest Only" to "Classic", exit back to my computer, right-click on the disk that has become raw to find the "Security" label, delete the garbled characters, and then add the user of this computer.

3. Use EasyRecovery software for data recovery.

I've been to it ... The U disk file is corrupted for no reason, and the file is important, and it can't be formatted, but can only be repaired. I looked for a lot of software, finally it is possible if you need it, please leave an email and I will send it to you.

There are many reasons why USB flash drive files cannot be deleted, and there are different solutions for different reasons.

Cause 1: The file is set to read-only. Once a file has been set with a read-only attribute, it cannot be deleted and must be deactivated.

Solution: The read-only file attribute is sometimes caused by a virus, but as long as there is no problem with other files, just right-click the file and select "Properties", and then remove the read-only option.

Cause 2: A virus is in the USB flash drive, and the virus runs the program. At this time, more responsible steps are needed to solve the problem.

There are many reasons why USB flash drive files cannot be deleted, and there are different solutions for different reasons. Cause 1: The file is set to read-only.

Reason 2: The USB flash drive was attacked by a sick macro, and the virus ran the program. At this time, the lack of travel needs to be solved by more responsible steps.

Some places that need to be paid attention to when using the USB flash drive in hidden search: 1. Plug and unplug the USB flash drive at will without bending, which may lead to data loss and damage to the USB flash drive; 2. Keep the safety of the equipment environment connected to the U disk, otherwise the U disk is easy to be infected with viruses; 3. Regular backup to prevent the loss of important files.

Dear, I hope to be able to help you, if there is something to do not fight the right place, you can continue to consult, I really hope to be able to help you! It's my pleasure to answer your questions! I wish you success in your studies and good luck in your work! <>

The files in the USB flash drive are gone:

It shows that the virus is quite serious, first check and kill the virus.

This is not data loss, can be recovered, it is recommended to quickly put the grid, otherwise the system will also suffer, then the trouble will be big! Format it!

You can do this,Format the U disk first,And then use the easy recover software to retrieve the files in the U disk but can't guarantee that the recovered files are good or garbled,Because it has been modified by a virus, it is difficult to confirm,You can only try it yourself,It may be due to the wrong way that your files are associated,See you change their file association files,As for what data recovery software,Is it useful?,And winhex,Can you use it?,So the first problem is association、 The second may be due to the exploitation of the encryption feature of the NTFS partition format, which is now hidden for some reasons. If it is a word file, there are two ways to solve it:

1. Alternate formatting.

This method is to save the corrupted word document in another format.

1. Get back the hidden documents, click the "File Save As" menu, in the "Save Type" list, select "RTF", then click the "Save" button, and close Word.

2. Open the RTF format file you just saved, and use "Save As" again to re-save the file as a "Word document", and now you can open the Word file and find that the file may have been restored. If the file cannot be recovered after converting to RTF format, you can convert the file to plain text format again (*.).txt) and convert back to word format.

Of course, when converting to a txt file, information such as ** will be lost.

2. Reset the format.

There is a hidden location in Word that is used to save all kinds of formatting information in the document, so just delete these formatting information to restore the file.

1. After opening the hidden document, click the "Tools Options" menu, select the "" tab, uncheck the "Use Smart Paragraph Selection Range" checkbox, and then click the button. This will allow you to repair the file.

2. Select all the content except the last paragraph, and then paste and copy the content into the new word file, and you can copy the important information to the computer first, and then format the USB flash drive. Make a backup of the data on the USB flash drive first.

Method 1: In the case that the USB flash drive is not poisoned, right-click on your USB flash drive to view the properties, if the used space is not 0, then create a new txt file in your USB flash drive and enter attrib in it to save. Then open My Computer - > Tools - > Folder Options - > to view, and uncheck the hidden known file extensions in front of it.

If it has already been removed, you don't need to do this. Then rename the newly created txt file to the new one. Double-click to run. If it shows that the used space is 0, then the next Easy Recovery software will do.

Method 2: Insert the U disk, and then don't open it, but right-click the drive letter, select "Open as **portable device", and wait for all the files to be displayed, but can't be opened, just copy it to the local hard disk, and format the U disk after the data is backed up.

Method 3: Virus reason, if there is a virus in the USB flash drive, this virus it constantly adds a suffix to your exe file, and changes the attribute to "hidden" and "system file", and at the same time generates a virus file with the same name as the infected file, so after being infected with the virus, your real file is not visible, and what you point to is indeed a virus file.

Click on the file properties and just remove the hidden tick.
