It seems to acquire the Forge version and modifying nothing else. It will do the 'update' process and download that ~20MB file, but it only does it once, so I can remove files that are about that size and see what it requests to download IF the launcher is never closed between doing these tests. ' ('asterisk.asterisk') and sort the results by recently updated, I can see files that the launcher is modifying under that directory. If I go to /Users//Twitch/Minecraft/Install/ and search for '. However, I have managed to narrow down what file it is likely downloading every time (maybe).

The launcher decides to download files every time it is opened, even if that's 20 times a day.ģ Completely close all instances of the launcher.ĭoing some looking around, I can tell you that my CurseForge system (That's literally everything involving it) is from before Overwolf acquired it, so it's still under the Twitch folder in the Users folder. The launcher should have all prepared files ready to boot up Java Minecraft every time I want to play, and no update has been issued to the game, or the launcher. Simply launching a fresh version of a Forge based Java Minecraft instance for the first time (As in, the first time the launcher was opened since it was last closed), the launcher will proceed to download a ~20-21MB file every single time, unless the launcher is left open between instances of actually clicking the 'PLAY' button.
