Hi there! I'm using a 1 Gb pen drive, and I've just noticed that I can't even change a file's name because the system says something like "the operation cannot be completed because the disk "x" is full. Delete some files and try again" (please note that my system is in Spanish and the translation might differ). The point is that I can see "85 MB available" in the status bar... Some files I can change them, some others I can't... I can copy some files and some others I cannot... What's going on here??
