USB stick problem

Greetings,
I have a problem with my USB stick.
I dont know how it come, but my 1gb stick turn into a 120 GB stick. Fakely of course.

Stick is drive H:
When I put my mouse on the folder "_yarı tamam" you can see this absurd situation :

The size is 63 GB ... (but actually not more than 800 kb - 1 mb)
And you can see the CRAZY names ...

And see the folder inside here : 2.jpg

Incredible. I dont know what is the reason for that.

- When I check "my computer", the drive H: seems 1 GB, normal. (3.jpg)
- When I scan with Kaspersky, (daily updated) shows no virus.


What I can say is this stick very very important for me, it s the novel i ve been writing for 1 years.
Please tell anything you know.
I ll be grateful of any helps.

Thanks in advance.


ps. I may be doubling my post, please delete if so. my first message here.

 

Updating my question.
Still valid. I cant progress much.

 

Hello,Hmmm never seen this before back everything up straight away of course you really should have many backups already of something so important,when the file is copied to your PC does the file suffer the same indiscrepancy?

What I would do if is buy a new stick drive if the file is that important to you then copy your file to the new stick drive from your computer or with the important files removed format the stick drive then re copy the file to it.

EDIT If you have no joy due to the file being a text file you can copy and paste the entire text into a new text document,that will fix it if all else fails.

 

Yes I could copy some of the corrupted text files to computer, but again they are same. When I open a .Doc file , it opens a document full of ascii codes or something.
I am attaching here a corrupted txt file, check the corruption. It should be a text, one paragraph.

I ve already bought a new stick by the way
