I'm hoping this is the right place. When working on my spreadsheets/I use LibreOffice. And I want to save the finished one. I can do so relatively fast for the file I opened it from. But when I go to save in another file/usually under "Documents" or one of it's sub-folders, it seems to take longer. Or if I want to save it to a flash drive, that takes even longer. Is this a problem of MS? Or of my 5 yr old PC? Or is it a LibreOffice problem? Or what? I do run C Cleaner, an A/V scan and all those things. Defrag. You name it. So if someone can maybe give me a list of what I should do. ? Example: which should I do first? The A/V, the C Cleaner, the Defrag, etc. So if this is not a problem of Windows, I apologize for opening this thread.
