I recently had a piece of work that was crashing repeatedly and so the AutoSave files started appearing as the new title on recovery. Normally I never see these files as they are erased when Sketchup closes correctly. Nice that Sketchup prompted the recovery on it’s own, with multiple crashes I ended up with several files with AutoSave prefixed 3 times in the file name. But @lukestar the AutoSave labeled files are deleted each time sketchup closes correctly as it’s assumed you no longer need it. I just checked, my Autosave folder under library/application support is empty. Are you looking for a backup of every file in the original folder?
