Nope.  DOS (COMMAND.COM) uses FCB's to do the deleting.  If you use the 
ASCIIZ function calls, you MUST call dosfindfirst, dosfindnext to get each 
file and then delete them (It is faster to read the filenames first and 
then delete them, I've timed it...)  With FCBs you just use the wild-cards 
and voila, all the files are deleted.  Of course that means that you can't 
delete selectively, or make sure you can delete it by chaning it's 
attributes.  My version of rm is just as fast as DOS on a local drive and 
under 100 files.  On a network or over 100 files, DOS beats it hands down. 
I can delete 600 files in 2.2 seconds with DOS.  It takes 1.5 minutes with 
my rm.

Curious, DOS 5.0 supports a /P parameter for prompting of each file name 
for deletion....  The damn thing is probably still using FCBs though...

(I've got to get a .sig file together... I find the default hideous!)
