WebDAV
Pagelove sites are modified via their own WebDAV mount that is unique for each site. The credentials used to log in to your WebDAV site are configurable in the main Pagelove coontrol panel.
It is important to note that the WebDAV mount represents a live, working site, and as Pagelove modifies the DOM in-place, it is possible that when it comes time to write a file it may have already been updated by a user of the site.
As the developer, you are resposible for taking measures to prevent data loss through the WebDAV process.
