Create file on FAT16 without long file names

I want to create a file on a FAT16 formatted volume and only create the
8.3 format MS-DOS style file name. I don't want the extra directory
entry for the long file name. Does anyone know how to do this?

Just don't use file names that are non 8.3 compliant.

This isn't just a question of length as some characters (lower case
letters for instance) will trigger long name entries. As long as you
stick to upper case alphas and numerics you should be fine.

Have a look at the GetShortPathName() function.

I'll give this a try. I was under the impression that CreateFile() made
a long file name entry even if this wasn't required.

Shouldn't do. I've just checked under Win2K and it doesn't do it.
