Hehe: There may be two possibilities. 1. Computer poisoning automatically blocks the files of your USB flash drive. Second, the computer deleted all the files due to improper operation (the possibility is zero).
So for the first case, you can first connect the USB flash drive to another computer to see if you can see the files inside, if you see it, then it means that the computer you are using is using a virus, antivirus. If you can't see it on other computers, you can open the My Computer-Tools-Folders option, select View in the pop-up dialog box - choose to show all files and folders, and uncheck the front of the hidden protected operating system files, select Yes, and then Apply, OK. Open the USB flash drive with the right click to see if there are any files.
If the above operation cannot show the hidden files, the antivirus is in operation first, or the USB flash drive can be connected to a computer without viruses to perform the above operations. If you can't see the files in your USB flash drive, you can only ask a professional to help you recover, hehe, but if you are lucky, you may recover 80%, and if you are unlucky, the file will not be recovered, but you have to give people money.

Is the interface plugged in? It is also not ruled out that poisoning is hidden. Look at the property to see if there is room for it. If there is, kill and kill the virus. If not, just plug and unplug it a few more times.

1. Inadvertently hidden: click "Tools" "Folder Options" "View", check "Show all files and folders", and then remove the "Hide extensions of known file types" option. Finally, click Apply.
2. If you are hit by a serious virus, you can check and kill it.
3. Use the following method to copy the dongdong out, and then format the U disk for a while.
1) Open a random folder, click "Tools" "Folder Options" "View", check "Show all files and folders", and then remove the "Hide extensions of known file types" option. Finally, click Apply.
2) Find one. RAR format compressed file,New can also be created,Then double-click to open it,Then keep clicking the up key,Go to my computer directory,Double-click the U disk,You can see all your documents。 (3) All the contents in the folder can be extracted.
Double-click on a compressed file in RAR format to open a folder you just saw, check the box except "...folder and press "Ctrl+C" and that's it. Create a new folder on the desktop, open it, and press "Ctrl+V" to copy the contents of that folder.
Others can be copied accordingly. Suggestion: Create a folder in the USB flash drive, put everything in this folder, and the virus can be replicated only once in the future.

It is estimated to be a fake USB drive. The quality is very poor.
-
Find a data repair software, as long as there are no more files in the USB flash drive, there is no problem in getting the files back.
-
My computer -- Management -- Storage -- Disk Management to see if there is one, if there is, just right-click to open it.

Will the USB flash drive be broken?,You can change the computer and try it.。

Maybe the first floor is right; There is also an explanation that you buy a USB flash drive that has been expanded to the car, that is, a pirated disk, let's do the math: suppose yours is a 2G USB disk, then the theoretical storage space is 2*1000*, assuming that your USB disk space is greater than, then the USB flash drive is pirated, if it is 4G, then only, it is a 4G disk, in fact, only the state jujube capacity, more than the value of this part, the file will be destroyed by the book sails, that is, the kind of situation you said, **can't**.

Hello, if you want to understand this situation, you must first know the structure inside the USB disk, the inside of the USB disk is the EEPROM data memory, its control principle is the voltage control gate transistor voltage high and low value, the junction capacitance of the gate transistor can save the voltage value for a long time, the main reason for saving data after power failure is to add a floating gate and a selection gate to the original transistor. A floating shed is formed on a semiconductor where the current is conducted in one direction between the source and the drain. The floating gate is encased with a silicon-oxide film insulator. >>>More
