ODS Files become corrupt too offen

[mostar]

Hello,

I’m updating my calc files on daily base. Every few days one of then become corrupted.
I don’t have any corruption problem with any other allocation.
It seem as corrupted zip archive.

Do you have any idea what can cause that?

Is the a way not to compress the content of the ods file (maybe it will reduce the corruption risk)?

Using calc 4.2.7.2 and 4.3.4.1 on Ubuntu 14.04

Thank you

Where do you save the files?, In a pen?

Files can get tangled especially if they have ever been saved as .xls or .xlsx.

Copy everything and paste it into a new, empty spreadsheet.
