This question already has an answer here:
Before I realised Steam had a backup option, I tried to manually back up my games.
For my game I have the NCF file, and the Game data (the folder from Steam/steamapps/common).
I have done the following
- I put the NCF file in Steam/steamapps
- I put the game folder in Steam/steamapps/common
- I restarted my computer
Steam still thinks the game is not installed and is trying to make me redownload it.
Is there a way I can let Steam know the game is there?
Note: I live in Australia, and we have download limits, so I don't want to redownload my whole game again.
