Weird files/ folders on the USB flash drive

Some of the files and folders become weird names, when I click on the weird files, the error message "The file or directory is corrupted and unreadable." appears.
Is there any recovered methods?

The name of files and folders just like in the screenshot.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

First step I would take is to run a chkdsk on the usb drive

Open My Computer
Right click USB drive
Select Properties
Select Tools
Click Check Now and let it repair the drive

The size of the files are hugh, see if the repair will help - did you have files on the drive that size to begin with?

Hi, I tried chkdsk, but not successfully repair.
The file's original size is a doc file and very small, but don't know why all the doc files renamed to strange filename and those size become very large.

Ok go with @erniebeek suggestion and get Recuva and see if it will recover the files

When you ran chkdsk did it fail? Or did it run complete without errors?

Hopefully the drive is still surviving...rightfully she have tested on clone instead to prevent further damages...also if possible scan with AV....

Some extract on discussion forum for Data recovery.The first link is freeware, the others are free to try before purchase. The last two are a slightly better product in my opinion.
