Thank you. Very helpful. It’s good that Postman does backup (I didn’t even know about it). I have recovered the files. Thanks to the Postman team for coming up with the idea of doing backup. By the way, I found the path to the backup file through Double Commander, otherwise I wouldn’t have seen it through a regular Finder.
