Today, 18 December 2020, I noticed that the last save of many frequently used libreofficecalc spreadsheets and Writer documents had not been saved since 12 Dec 2020, although I use these files many times a day and save frequently. Is there any way to recover the more recent files? I have tried data recovery (Recuva), Wise and other searches with no success but it looks like I will have to try and reconstruct those files, as it appears that the save function did not work, and there were no error messages, which is why I did not realize the data was not getting saved.
I am using libreoffice 184.108.40.206 and am reluctant to upgrade to version 7 because I tried the first release of version 7 and I was unable to use the program until I reverted back to version 6.4.
I am using Windows 10 release 2004
I took the 12 Dec files and put them on a flash drive and they updated fine. I check-disked my hard drive where they were originally stored and Checkdisk found no errors. My many backups did not help because they were only backups of unsaved files.
I did go into safe mode and reset the user profile and then tried putting the files on another drive and was able to save them.
I have given up hope of recovering the up to date files, since it looks like none of them were up to date, but can anyone help explain what happened and what I can do (besides verifying the saves) to avoid this in the future so at least I get a warning of some type when the files do not save?
