WebPlus X6: Where is Web Plus X6 saving my files....?

Hi... As I'm working on my new website, I see why instructions for WP6 state to save frequently. It crashes very, very frequently. So fine. I get that. But what I cannot figure out is where is it saving the files? When WP6 crashes, it reopens itself with all kinds of saved versions of my pages. Some I deleted long ago. I have done a search on my computer and WP6 still brings them back. ( I have even deleted them out of the recycle bin) Has anyone else experienced this? I now am up to like 17 pages that appear out of who knows where.

Thanks for any and all suggestions.
