Mod downloading and saving as a text file.
When I download the mod file and I open the file location it turns out to be a text file but i'm not sure why. Inside the file is some random weird letters that I have never seen before. Ó%tÀ; w [‚ × .žJ3. These are some of the contents of the file. The file extension is .rar.
Make sure 'Hide extensions for known file types' is unticked in Windows folder options (Google for instructions on how to access folder options. Edit link to include OS (Win 7/8/10 etc) you have installed).
Then have a look at the file extension again. Is it '.rar.txt' (or something similar)? If so, remove the '.txt' etc part & confirm the change of file extention to get a fully functional '.rar' file back.
Installing 7zip or WinRAR should fix it, as long as the file extension becomes associated with the program you install. I believe both programs have built-in ways to set associations.
