where filepath/ is ~/.minecraft by default but yes, could be anything
Why:
let's say I have two drives, SSD and HDD
all games go to HDD because SSD is smol
so my Minecraft may be in D:/ not C:/
well tbh it doesn't matter where the launcher is
but lets say I keep my .minecraft in HDD as expected
so also the version jars etc
now I do want to install FO on it
and if the installer runs from SSD, it may not find Minecraft at all, hence the folder path
and the checkbox will state whether I want to overwrite contents or put them in subfolder
does that make sense?
Why:
