Batch file question using native ftp.exe program....

I am currently using a batch file with an ftp.exe script to 
MGET *.XYZ   and then MDELETE *.XYZ from an ftp site.
This worked well, until it started deleting files that were never downloaded.
They were added during/after the MGET so they just get deleted.

The files are numerically sequential files but I have no way of
knowing the current number.

Is there anyway make this work with just Batch File & ftp.exe

I tried to REN *.XYZ *.PEN then DL & deleted those, but you can rename
with wildcards...

You can't pass command line parameters to ftp except for pre-made scripts (i think)

There is no delete after download option that I know of.

Is there any way to make this work...

I was thinking it might be possible to do a local "IF EXISTS" then an
ftp delete, but I don't know the file names.

Can a list of filenames be downloaded then used?

Are there any other DOS programs that can run in a batch file that
could do get first, delete first?

I am perfectly ok with Get/Delete one by one.

I would prefer to continue using ftp.exe if possible.

Thanks,
