I recently installed Libre Office an ODT file will not open as message says its corrupted and recovery fails

I have scanned the file and no bug exists it was saved perfectly well the night before. How can I open this file it is 10 years work!!! My computer is a Lenovo and works on windows 8.1 Please can you help?

This is obvious spam-bait. Soon enough, spammers will flood in with helpful links to data-recovery products. Just how many posts saying “my file is corrupt & I cannot recovery it” does this site need? Are it’s users unable to search this site? Perhaps they need spam for intelligence-boosting energy drinks instead.

Too right, @Alex_Kemp, too right.
