Corrupting files

I have been using 6.3.4.2 for many years because every time I upgraded, Libre would not work and I had to go back to 6.3.4.2. I recently purchased a Win 11 machine and loaded 24.8.4. The software seems like it loads ok but I found that saving a file to my NAS for sharing with the old computer, the files are corrupted. Similar topics here don’t answer the specific problem. Should I just drop back to 6.3.4.2 on the Win11 computer? Or…??

Start to find or solve the problem. Obviously your install is a bit different from others, wich does not show your kind of problems.

1.When I read something like “the files are corrupted.” the first step should be to create backups. Put some on a USB-device and try to load them on other computers, because a backup wich can not be read on other computers is no backup (if your old hardware fails.)
2. Your text seems to imply saving one file is corrupting more than one file?

But step by step: Does this corruption also shows when you transfer a file via USB-Stick? Any encryption activated on the newer computer? Precise error shown by LibreOffice? Can you rename such files to test.zip and open in Explorer (Windows)? Share a test-file from old/new computer so others may check, if they can be loaded.
3. What security/anti-virus do you use? Interfering security, wich only accepts your old version of LibreOffice as known may be a cause of your problems.

This now looks like a bug report item. The issue only happens when 24.8.4 writes a pass protected file to the NAS and then 6.3.4.2 sees it as corrupted and not password protected. Since I cant update my 6.3.4.2, I am taking out passwords until I can rid myself of the old Windows boxes.

Not really necessary: You can save in older versions of the file formats (also necessary to exchange files with Openoffice).
.
Quoted from above link:
“To disable this feature, change Tools ▸ Options ▸ Load/Save ▸ General ▸ ODF format version to a version that is not “Extended”.”
