So I was trying to install "Valhelsia 3" to play with my friend on his server. But whenever I try downloading the modpack it keeps coming up with an error message saying "There is not enough space on this disk." The disk drive that I have the mod installation path linked too is the drive with the most space in it. Enough to download the same modpack more than 80 times.
Even if you change the location the app saves its packs too it will still download temp files to your Local(C) drive where the app itself is saved. With this said, you need a minimum of 10gb free on your local(C) drive. This should be done anyways for good pc care as if your drive is running out of space your pc itself will also start running into issues as well.
