Hi Sharayu,
Try deleting the files using DOS.
To start it type "CMD" into the Run box in the Start Menu.
From there at the command problem type in the following
e:\
If your pen drive appears with a different drive letter when you plug it into your computer then substitute e:\ for that drive letter in the above command
Then type:
dir
This will list all the files currently on your pen drive. If the file is corrupted you may notice that the file you want to delete has a different name in DOS then it does in Windows. So make sure you use the name of the files as it appears in DOS in the below command
To delete type in the following
del thefileiwanttodelete.txt
Hope this help

well i did exactly that, but when i do the last step i get a warning from cmd.exe that the file is corrupted and is unreadable. I don't really know what to do now, since it can't even be deleted with CMD. and by the way it has the same name in CMD as it has in windows explorer
