So you've got some pregame editor files that you want to install into your Football Manager.   If you don't know how to install them, just follow these steps   Step 1 - If you download a compressed file (zip, rar, .7z, etc) If you downloaded a compressed file (archive) first, you must extract them, before continuing, otherwise it won't work.   On the other hand, if the download file is not compressed (ends on .fmf) you are good to go to the next step.
