I have a couple games I had downloaded and installed before I downloaded GoG Galaxy client. Divinity 2, Enclave and Outcast. Well I used the scan feature and it found Outcast, but it didn't find the other 2 that are in the same folder.

It's not a huge deal I would have just liked to have them in my Galaxy library to select, I know an option would be to uninstall and redownload, but I just downgraded my internet from 200Mb/s connection to a 15Mb/s connection (yeah a big downgrade, roommate is moving out had to cut the budget) So I'm not very keen on redownloading the games on such a slow connection.

There's an Import option for games that Galaxy doesn't detect.

I haven't used it for months so I couldn't tell you where, but you should find it if you poke around a bit.

Ah I found it, on the install page there is an option to import folder. Thank You.

And it doesn't work with every game. I've found that while I've installed them the same way it's designed to only detect some of them. I don't have the bandwidth to downloaded everything through Galaxy uncompressed just to manage them through it personally.
