So i bought a big external hard drive and want to save all my gog games there and i would like to know what is the fastest and easiest way?Just from the official site would be a bit tidious so what about installing galaxy on the hard drive and download the offline installers from there?Does anyone know?Lg

Using Galaxy won't be much less tedious than the website. You'll still need to click each game individually, click Extras, then select the offline installers and any additional goodies.

The most efficient method would probably be GOGRepo: https://github.com/eddie3/gogrepo. You'll need to install Python and use a command-line interface to execute the script, but the commands are pretty straight forward. You could even set up the scripts to automatically run on a schedule (i.e. every Sunday night at 3am, check for and download any new updates to your library).

I second gogrepo, particularly because of its file verification feature. I had downloaded my entire collection through Galaxy last year, and somehow, a significant amount of them were corrupted. With gogrepo, I could identify them and replace them with working copies.

There was a small caveat for me, as I play most games in English, except those made by German developers: You can specify which languages you want to download games in, but then it will download these language versions for all games, if available, so now I have German copies of games I won't ever play in German, and English ones of German games. But I can easily spare the additional space, and it's just much more convenient than downloading manually or through Galaxy.

It seems you can download the games only with galaxy now at least i cant download them manually

You can download the offline backup installer with any modern browser. What's the problem?

For larger libraries I second gogrepy.py, it's actually running right now here.

When i click on the game it just downloads a small file and when i click on it it opens galaxy....what do you mean with gogrepy?

Dunno but it seems to work fine for me. You have to click on "Download Backup Offline Installer" at the bottom, not the "Download and Install" button which opens Galaxy?

gogrepo.py is a Python script that can download and update your whole GOG library (offline installers, bonus material etc).

It's a bit of an effort to set it up, but once you got it, it's very convenient.

Do not click the blue "Download and Install Now" button. Click the one below it.

as others said just use gogrepo
it takes like 10 mins max to set up but then you just run it and it gets all the updates and new games with all the extra stuff ,neatly ordered into folders and thats what you want
