Hi Ian, My understanding is that this folder contains snap shots of files/projects that are created as a backup. You can set the number of Snap shots to keep in the Qt Ide configuration file (see Edit|Configure|Qt Ide) You can compare the currently open version of script to older versions using Script|Script Snapshot. You can create project snapshots using the Project|Make Snapshot.
Having said that I haven't used these features much. Chris Burke will probably be the best person to explain any intricacies.
