I've noticed this on a couple different occasions now. Sometimes I will open Thunar and do a quick "right-click", "copy" a directory -- then click over to my USB flash drive and "right-click", "paste". The problem is on the newly copied files, uppercase letters in the file name have been converted to lowercase. In my limited testing, this only seems to happen when copying from my hard drive to USB flash drives -- this does not happen when copying hard drive to hard drive. In this picture I copied the entire "cdparanoia" directory from my hard disk to my USB drive. http://www.eng.utah.edu/~ncrandal/images/thunar.jpg

I guess the file system driver does that, because Thunar itself does not change the case of the file names. Try to copy using cp from the cmdline.

Thanks for the help, sorry for the trouble - we can delete this / mark this as resolved.
