Yesterday, I cancelled an installation on GOG galaxy, and it still has not returned the memory it allotted. This is such an awful software oversight I'm considering washing my hands of the company to be honest. I am sick of waiting for the cloud to tell my PC it released the memory. The galaxy has no way to manually clear caches. Is there something i'm missing? Or is GOG about to lose a customer over nonsense?

Did you try clearing cache manually, checking temporary folders to see if you can find any files you can delete or downloading the game again with Galaxy to see if it overwrites any leftover files?

And a bit off topic, but personally, I'd suggest not using Galaxy. gogrepo or gogrepoc may be better options for downloading GOG games, and Playnite for having multiple libraries in a single interface.

This ^. I think you're using GOG in the wrong way.

The store really shine when you take advantage of its main differentiator: Offline installers with no extra bloat tacked on and no online dependencies.

Otherwise, in terms of downloading client, beyond gogrepoc, there is also my own and, lgogdownloader if you are on Linux:

https://github.com/Kalanyr/gogrepoc
https://github.com/Sude-/lgogdownloader
https://github.com/Magnitus-/gogcli

Or if your collection is small, you can always simply download your games via the web interface provided on the GOG website which is also quite serviceable (although it doesn't scale well when your collection grows). Enjoy.

Guys, OP can't even delete temporary files and you're suggesting him to use command line tools?

Fair enough.

Although I'm not ruling out putting a web dashboard for user interface driven management in mine, but realistically, the earliest for that would be late next year.

After sinking thousands of dollars into my collection here, I want a first-rate experience managing and accessing my collection and I don't care if I have to do it myself, in the end, it will be beautiful.

PS: If I could, I'd totally reverse-engineer the Galaxy protocol after that and see if I could self-host a Galaxy-like server on my LAN for local multiplayer, but legally, that might be pushing it. Imho, GOG should do that themselves. They'd have takers. They got it wrong trying to be another Steam. They don't have the resources for that.

I don't use Galaxy, but try running Disk Clean-up in elevated mode and clearing temporary files. If that doesn't work, you could try doing the installation you cancelled and then uninstalling afterwards.

There is also a separate forum for Galaxy issues:

https://www.gog.com/forum/general_beta_gog_galaxy_2.0#1634495818

This is why I can't remember anything.

Woa, you have cool plans for the future.
I wish Gog improved Galaxy and their website too, but sadly they aren't doing too well at the moment.
I hope it will be better next year..

This.

restart the system will always clear any memory
it's also worth tell Galaxy not to auto run at Windows start so you can decide for yourself what software gets to use the internet and download files... I know that is not PC now days ;)

Thanks. I'm not sure about the legality of reverse-engineering the Galaxy protocol part. My googling haven't been promising so far (Gog specifically includes a reverse-engineering clause in their Eula).

I believe that's what Linux did with Samba and Git was created because Bitkeeper kicked out the Linux kernel from their platform after one of their guys reverse-engineered the Bitkeeper protocol (see https://en.wikipedia.org/wiki/Git#History) so there is some legal precedent, but even if it were strictly legal, there is something to be said about antagonizing the platform holder (in this case, GOG).

Overall, between their radio silence, lack of open api for pretty much anything they have and lack of inclusiveness with their Galaxy efforts, I get the impression that the management at GOG may be a little old school (ie, pre-open source mindset)... probably not community building material, at least not from a technical standpoint.

The galaxy doesn't have a feature to clear the cache manually. It says if you log out, it clears it automatically. Yet, I've logged in and out of gog and galaxy, uninstalled the galaxy, uninstalled my mod manager and mods, cleared temporary folders, then went back and cleared out every folder under GOG and Galaxy. The memory still has not been freed up, I uninstalled another game to play the one I want. I've noticed this before, and after several days the memory will magically pop back up. I think it's a hiccup between caching with galaxy and my pc specifically when not fully installing a game, or installing/uninstalling.

Anyway, I was hoping for a fix that would circumvent me having to rotate games when I buy something, oh well. Another reason to buy a better rig. Cheers.

I don't know either, but it felt like a post-Gog multiplayer preservation project.
It's not exactly needed as it is now, but maybe in a grim future..

And Gog's rejection of open-source seems indeed weird, knowing CDPR's "grey-market" origins.
Maybe they're worried that people will start using the fork more than the original lol (and then ask for support).

Laughed out loud there, that was great!
