All installations are stored within the /home/minecraft/* directory within their respective folders...
Minecraft: /home/minecraft/mc-instances/* - See here for extra information on Minecraft instance identification.
Have you ever tried to change mods list (mods-list.json) for Factorio via sFTP/File Manager, but it is not working or loading any mods? Or thought "Hey, why is my uploaded Terraria save not working?", you may be the victim of a hidden directory!
Some games will store the information in a hidden directory, on your home computer, this may be located in the %App Data%. However, most of our services run on Linux CentOS, Linux does not have a %App Data%, instead, it stores these files in hidden directories such as /home/minecraft/.local/, the full stop in the directory name makes the directory hidden by default.
Note: Never remove or edit your .ssh .pki directories, you can break your service!
