I was working on several Writer documents when Libre Office froze (as it does very occasionally), so I force-quit and relaunched.
All the documents are ok except for one, which was very large. When I try to open it, I get the message “filename is corrupt and therefore cannot be opened. Should Libre Office repair the file?” If I click yes, I get the message “filename cannot be repaired and therefore cannot be opened.”
The backup folder is completely empty, and unfortunately I did not have “Always create backup copy” turned on.
Any suggestions for how I can recover this file, or find a previous version of it?
