So I downloaded Freearc 0.666 for my 64bit Windows 10 computer. But, the problem is that it won't compress files at all. I've tried uninstalling, then reinstalling, but to no avail. When I'm adding files to the archive, I am definitely "Maximum Compression". I've tried pressing the save button to see if that helps, but it doesn't. When I look on Youtube the tutorials look so easy and you can compress massive files into tiny ones.
As an added note, on the Youtube videos the compression rate is something like 0% but mine is nearly 100%. What do you recommend I should do?
