RI> Hello all!

RI>    I have been working on a file manager for sysops of boards that use a

The double quote is an invalid character! It will simply disappear
from the filename

Cdroms are generally written the the iso9600 format which is 8.3
filenames and the character set is the alpha-numeric character set..
one invalid character that I know of is the {at}

tested, use

anyone know of a

if you can use the filename to open the file or findfirst/findnext
reports it as the filename then you can take it for granted that it is
the filename.  In otherwords let the operating system take care of
it.. You might want to 'warn' the sysop of a filename that does not
follow the 8.3 specifications. (dos apps won't see it)
