And in V6, they are deleted and moved to the Recycle Bin.
If you haven’t been clicking Save yourself, and updating your 3dm file, then you may be able to find a recent version in the Recycle bin.
UHHHH @John thanks a lot! All safe! Thanks so much!!!
Maybe you could implement a note in the autosave section and an option to rule the behavior yourself, as I want to keep all Autosave files in folder and have them replace with the most recent file. But seems to disappear also to the Recycle Bin when file is saved. So maybe even the incremental save could be inplemented in this single Autosave section in options.
Concerning the autosave rhythm with big files the Recycle Bin could pile up.
