Can't post code at the moment but google for a php .zip class. Then you just loop through, create the user specific .torrent files, add them to a buffer and then write/output the .zip file outside of the loop at the end.

sharpie

no m8 when a members hard drive fails he/she can just pop on site and download all their uploads in one go in a zip file ive seen this on gazalle source sites but not tbdev

MelvinMeow

You mean in the sense of downloading the backups of your /torrents/ dir?

sharpie

is there a mod where you can download all your uploaded torrents as a zip file rather then download each and every torrent file one by one

Thanks in advance
