SFTP / Garrys mod

I can’t connect to the SFTP connection (see picture) and I don’t want to spend 1 hour searching for that god damn path. Can someone tell me the path for a Garry’s Mod server.

You should track down why you can’t connect. You shouldn’t access the instance data from outside of AMPs sandbox. If you use root to upload/manage files then you will damage your installation. Make sure the port that the SFTP is using there is accessible.
