Hi there,
this is not strictly an XP issue but I could see anywhere
obvious to post.

I am using the FTP command to periodically download and upload files. For
the download, I am issuing an mget * and then an mdelete * command, The
problem with this is that there is the potential for a file to arrive in the
remote folder between the download and deletion commands, meaning that files
can be missed.

Anyone have a more elegant solution?

How about using a different tool than Microsoft's FTP, like WGET. You
could invoke WGET twice, the second time with the "-N," or
"--timestamping" switch. It will retrieve only the files that are newer
or weren't there the first time.

WGET can retrieve files by both FTP and HTTP.

Depending on how good a script writer you are you can do this in a script:
1. log on to the ftp site
2. mget the files
3. log off ftp
4. redirect a "dir" list of the files to a temp file
5. massage the temp file into a list of ftp "del" commands.
6. log back onto the ftp site and use the temp file as a command file (-s
option)

This would be doable but painful in cmd shell, maybe not so bad in vbscript,
very easy in a *NIX shell such as bash.
