How can I install Unreal Engine on a drive other than the C: drive. I see some other people asking this but I don’t see a solution posted. I try to install the launcher on an alternate drive, but after it installs it always install the launcher on the C: drive no matter where I point it too. I have uninstalled it off of the C: drive and rebooted but it always goes back to it’s default location.
Do you want the entire launcher [C:\Program Files\Epic Games\Launcher] installed on a different volume, or just the engine [C:\Program Files\Epic Games\4.6] and project library [C:\Program Files\Epic Games\Launcher\VaultCache]? If you just want the engine and project library installed on a different volume (due to limited storage space, such as when using a SSD), then you could create directory junctions within Windows. For example (performed within the command prompt):
MKLINK /J “C:\Program Files\Epic Games\Launcher\VaultCache” “D:\Unreal Project Library”
There may be a more elegant solution within the launcher that I am unaware of.
