Is there a way to make a make a file on a ftp server

[qwerty]

I can not make the file a head of time because my program looks at the time stamp of the file that i upload to this ftp server. I would have to write a script to make that file, and overwrite my previous file and hope that flashfxp would still upload that file if i schedule it ahead of time.

If i can not make this file, then i would have to come in at mid-night to manually make that file and then upload it.
