Filename Checker

snoitami

Can anybody help im looking for a simple program that checks to see if a filename and extension meets the DOS 8.3 criteria

Many thanks if anybody can help or point me to somebody that does know.

There are two ways of doing this.
1. Try to creat/open the file. If you can, then it is valid, if not
then it is invalid.

2. Go through the name array one byte at a time.
If you hit more than one "." it is probably bad.
IF you hit any special characters "", "?" then
it is also bad. If you make it to the end of the
filename, it should be okay.
Oh, also check number of characters before the
"." and after. (8 and 3)

So you should have the variables
num_before
num_after
total_chars
valid_name
