​In Linux (or any UNIX like system), you can schedule tasks to be run by
using "cron" (do a "man crontab" for some information, if you need to). So,
if you can make a "shell script" which does all of your work without user
input, then you can use "cron" to schedule it periodically, every "n"
minutes, daily, weekly on ???day, monthly, etc. I don't know Filezilla, so
I don't know what you are really doing with it.

Windows has a similar scheduler to run "bat" files or "Power Shell"
scripts.​ I don't _DO_ Windows! <Start> -> <Administrative Tools> -> <Task

​If you are using Filezilla to copy a file, where is it being copied to? In
UNIX, I'd see if I could use just the plain "cp" command (for local, NFS,
or CIFS attached places) or either the "ftp" or "scp" command to copy to a
different server. In Windows the "copy" command could be used to copy the
file to a different folder locally or on a "share" (Windows "share" is,
more or less, the same as UNIX CIFS, if you're interested)​. Again, if this
needs to go to some other server, then a scripted "ftp" should work. One of
my co-workers does this.
