File is 60 TB?

I went to open one of the folder in my Sandisk extremem 3.0 64 GB drive.  The folder is full of files I never put in there, and it says that  the size is 60 TB!  I tried to delete it but it just says:  “Prepairing to delete” then does nothing. 

How do I clean this out?  I am running Windows 7 64 bit.


Sounds like an defekt in the file system. Try running chkdsk on it, also available via tools tab of the properties window of the drive in the Explorer.

Wow! 60TB. Anyways, try to reformat it if it’s an option. Have you tried to plug this to a different cmputer and see if it still says the same thing?
