Just to put in an uninvited two cents: When I started looking for methods to share my girl files, I looked at torrents but didn't like the way the operation worked. I chose Mega.nz instead. I think you should consider Mega, too.
Mega.nz is great for data sharing up to 50 gigs. Get a free account. Download the megasync tool. Set the bandwidth that megasync can comfortably use in the background of your network connection without impacting other needs. Point megasync at the directory containing your existing character files. Generate a secure pointer pointing at the umbrella directory on megasync. Publish the pointer.
After the initial sync period, you do not have to maintain or seed a torrent - all the bandwidth is between the people wanting the files and Mega. You aren't involved. Then you just maintain your girl files as normal, and if you leave megasync running, everyone automatically gets access to your updates instead of you having to rebuild and disseminate torrent files.
Just saying - it's pretty trivial that way. Mega is maybe not the be all and end all for all data sharing solutions, but it beats the heck out of torrents. Torrents are slower for the end user to download, harder for the creator to maintain, and have a constant drain on your network and computer even if you aren't changing anything.
You don't even have to zip up anything. We all know the girls directory structure, so we can find what we need. Just because I zip each girl up individually, doesn't mean it's necessary. In fact, I've been considering converting over to a non-zipped directory myself. For image and animated gifs, zipping doesn't really save a lot of room - it's mostly just for the convenience of downloading one file instead of three or four. But get this: Mega allows the user to select a set of desired files, and then download them as a single zipped file! Which means you and I don't need to zip anything up - Mega will do it for the end user as they desire.
