Scene File/Archive (2)

Unable to open or save files (3)

Why does the scene file fail to open/crash/run out of memory/report a TDR error?
Why can't the file be saved, and why does it show a prompt saying it has been moved or is corrupted?
Why can't the file be opened, prompting that the project file is corrupted?

History version or backup files (1)

How can I check history version/backup files? What should I do if I forget to save?
