Re^3: Removing Bad Characters from a String

That's the list for NTFS, in FAT, more characters are banned. On the top of my head, I think the additional ones are \x20 + = [ ] %

I think that control characters (\x00-\x1f but not \x7f IIRC) and backslash (\\) are also banned in filenames, despite that error message not mentioning them.

actually, i'm not sure about your assertion that those additional characters are banned in FAT. i'm running on my parents' win 98 machine, which has a FAT filesystem (i first assumed, but then i checked, and it is FAT). i successfully named a file 'a[0] += 7 % 3.txt'. this is also the OS i got my error message from. i'd upload a small image as proof, but i'm not really sure how.

I think you are right. Those extended characters are allowed in windows long filenames (vfat). I think however that DOS 6 does not allow any of them.	[reply]
