I downloaded my files and spreadsheets from windows XP to windows 10 a month ago, went out of town, came back and could not open anything I transfered.
Why? What happens when you try to open a file?
I updated my windows 10 computer and the update must have reloaded the Libre program. I am now able to open all XP transfered files.
