The backup folder lable itself may well be ***folder name BK*** or similar, without the *'s.

If so, then either in Temp folders or in recent docs folder would be logical locations, but only til such time as the next reboot of the computer. And that timeframe in turn depends on the Temp folder setting of how long a given folder or doc within it is retained.

I'm sorry I can't be of more help, but at times I've struggled with the same issue, though with writing rather than 3d work.

I wish you every success in recovering the relevant folders and files.

Kind and Respectful Regards, Uyraell.
