Thanks for your reply Harvey.
Like i said usually i go to settings in Steam and choose the folder SteamLibrary2 but it isnt visible anymore.
I created this folder myself a few month ago and it did work until yesterday.
Normally when i install a game Steam asls where to install and i had 2 options.
Now there is only 1 option.
When i go to storage on Steam and click add folder i can
t find SteamLibrary2.
I was confused after installing the settlers because when i clicked on show files in folder it didnt open.
Normally it should be easy to find the folder because it
s more than 100GB in size.
edit:
Found the folder.
/home/mike/.var/app/com.valvesoftware.Steam is hidden but the SteamLibrary folder is not.
