I use (and have it much bigger) drive
D: to store all my user data and games, but I have installed the Steam client on drive
C:. When I was installing a first game (Warhammer 40000), I've chosen to place my library folder on drive
D: and the game went there.
But now as I've got installed the second game (Portal), I can see that it was put on drive
C: despite to the choice I've done previously. When I open Steam - Settings - Downloads + Cloud - Steam library folders, I can see both installation places in the list. Can I merge them into one?
I would even agree to use the default drive
C: library (as I've replaced it with a symlink already). When I press to remove one library it says it can only remove empty ones.
