I downloaded libreoffice 5.4.6 and it turned all my .rtf into spreadsheets without my permission. I deleted it from program files hoping it would change back and made it even worse since now I can’t open those files at all. I obviously downloaded the wrong libreoffice. How do I fix this?
From where did you download?
And what exactly does it mean “turned all my .rtf into spreadsheets”?
I suppose that OP has filetype associations changed for RTFs, so that they now open with Calc by default; or possibly simply use Calc icons…
