        Uh, fellas, maybe y'all should step back and think for a second.  
Sure, this well may be a bug in the df.exe program, but it is actually a 
blessing in disguise.  The problem here is not really the df.exe, but rather 
the fact that someone is using a computer with a 2 gig partition.  This makes 
absolutely no sense.  You guys do realize that it doesn't matter how "big" a 
hard drive is, in DOS, it can never contain more than 32767 files per 
partition.  You're wasting a ton of disk space by setting your cluster size to 
64K.  So maybe rewriting df.exe isn't the solution to this problem, but 
rather, repatitioning your disk to something reasonable is.
