When you see the GOG Galaxy Launcher Insufficient disk space error - try moving PC games to another drive - this is the sort of solution that most in the gaming community would suggest, but if you don't know the correct way to do this, things can get tricky. Don't worry, use this tutorial as a troubleshooting guide.
It is common to witness PC game installation errors due to insufficient space. To solve this problem, you will need to create more space on your main drive or move the temporary folders to different drives. Here's what you need to do:
You cannot install the game if you do not have enough space in C drive. It requires 35GB or more space.
When you install a game through GOG GALAXY, it first downloads the game files to a temporary game download folder located at:
C:\Program Files (x86)\GalaxyClient\Games\!Downloads\temp
Now, when you get the low disk space error while trying to download the game, you will either have to free up disk space on the C drive or change the Other Downloads folder.
So, navigate to the GOG GALAXY Settings panel by clicking the gear icon at the top left, and choosing the Settings optional.
Then proceed to the Installation, update tab visible under the GOG.GAMES section. Here, edit the following entries.
Simply press the drop down button next to the 2 entries above and select the Custom Folder entrance.
