calc file protection

I saved a Calc file in LO 24 and now can’t open it with LO 7 in another laptop as a warning box says the file is corrupted and LO can not open it. The message offers to try to repair it but that does not work…

Can it be opened on the originating computer? If it was transferred by USB and the drive was not properly unmounted then the file might not be fully copied to the USB drive.

See Preventing data disaster - The Document Foundation Wiki

yes the file can be opened on the original PC by Libre Office 24, then the file has been transferred in another PC through the cloud and here Office 7 can not open it

Some possibilities to try:

  • Safe mode on the LO-7.x device. Recently I experienced “endless” loading of some database-reports. Then I switched to safe-mode (from help-menu) and via file->open could load the files. Backup and reset the profile in this case
  • Check via checksum etc., if the file you load at LO7 is really identical to the one on the source computer. Or just transfer the fille again from the source. Just to rule out errors during transfer…
  • If the file is not too confidental, consider to share (upload) it here for inspection, so others can test, if this is only your configuration or a general problem, wich may need a bug-report.

Tried in safe mode with no avail, same “the file looks corrupted” warning.
I also tried with another Calc file pw protected with LO 24 and got just the same message in LO 7.
It looks there is a fundamental problem with the password encryption in LO 24 and LO 7 decryption…

Yes there is. Check release notes. You didn’t mention encryption before.

You will need LibreOffice 24.2 to open these encrypted files.

But it should still be possible to use the old encryption…
