How can I zip a folder up that's already on a server?
 

Linux. Google is worthless right now.

Thanks,
Bill

install the package "zip"

and read the manual page with "man zip" after...

works fine ;-)

You can also telnet in and use the tar command...

tar -cvf filename.tar directoryname

The above command will archive the directoryname and all sub folders.

Replace filename with what you want to call the archive and replace directoryname with the directory you want to archive.

go to the directory where you want the zip to be created

zip -r backup.zip /full/path/to/the/folder/you/want/to/zip/

On-the-Fly Zip
 

Just an idea: You can use On-The-Fly zip compression algorithms also so you don't need to store the media data twice - in the case if you wants to zip the content behind the members area just to enable to download it with one-click.

Have you got a shell account to the server or just FTP access?

If you got shell, the mentions above are right.
