I want to change txt files to open with a specific .xls it used to work but for some reason now it won't save anymore when I set the .xls program as the default.
It's a serious pain to have to open each txt manually and change it to xls. I want them to just all open with this spreadsheet program instead of WordPad again.
I have Windows 10 x64.
