Direct Links
Your files are optionally available as a direct link - http://yourhostname.swmirror.com/yourfile.exe (or you can use your own domain!) - so there are no confusing script names to remember.

Expiring Links
Create links that can only be downloaded a certain number of times or that expire on a certain date.

Password Protected Links
Require users to enter a password before they can download.

Combined Link Protection
All of our link security features can be used together so you can, for instance, create a link that can be downloaded X times until Y date by users with the password.
