260 is the typical limit. NTFS allows for 65535 per filename and I think up to 65535 deep on directories (I could be wrong on the second one). Win32 on the other had usually caps everything at 260 total (MAX_FILE_LIMIT). Most of the docs and examples out there use that. I would bet that it is some sort of FAT limitation. This can be annoying if you move a drive between differing OS's and the NTFS bit on the other side does interesting things. NTFS is also case sensitive. But the win32 layer 'hides' it mostly, there is a flag to turn it on. Unless you do something like write from a linux box and you can end up with 2 files named the 'same' but different case. It is also possible to trick windows into doing it but it is tougher.
