filename length, database

As an old Amiga user I have to admit that I teased Windows and MS-DOS users back in the days when their filesystem allowed filenames with only 11 chars (8+3) I was active Amiga user from 1989 until about 2004 and I still use it sometimes through emulation. But trust me, even amigians dont use that long filenames and 255 characters is enough

I dont recommend restricting the filename to 20 chars. It should be little bit longer than 20 chars as that can be too restrictive(by looking our customers filenames uploaded through CMS or eshop, theres quite long filenames for some). Remember that even if YOU dont use filenames longer than 20 characters, that doesnt mean users doesnt. Make it big enough so 99.9% are covered and give error message to person who exceeds a limit lets say 100 characters.
