Thank you

I'd settle for GOG providing the checksums so I could check them on my end. There's a long-standing wishlist entry for that simpler feature, and it's got more than 650 votes in it.


PS: I don't really understand your wishlist... You drag-n-drop a local file to a form in a website, and it allegedly tells you that file's checksum, no matter how big, and in a matter of seconds? How is that sorcery supposed to work?

I doubt that Gog will provide such feature outside of Galaxy.
Btw, if they at least reported their checksums, we could calculate ours with some free program, like HashMyFiles.

Yeah.. also this.

I didn't understand it either, but I just googled how this would work and from what I've seen timmy010 might be talking about the browser calculating the checksums locally, without uploading the files to the server.

So you'd be running a script (provided by GOG through some web page) in your browser instead of some standalone checksum program, which actually sounds pretty cool to me.

Timmy! (Sorry, couldn't resist :o)
Why would we need one, no sarcasm just trying to find a valid reason. You are aware the installers have their own Check Archive is valid function, look under options when you install them.

Thank god! I read that three times and I still have no clue what it is.

Thought I was the only one.

Try this address . Also the featurs is a bit more complex than simple check :)

That makes a lot of sense, yes. Thanks! Correction: Windows installers might have this function, but Linux ones don't. So it'd be great if they just displayed the MD5 checksum for at least the Linux installers.

That's usually how you go about integrity checks, yes. Not sure what the OP is looking for with the drag and drop option...

Edit: Ok, got it now... but JavaScript md5-calculating functions are infinitely slower than other checksum utilities you can run locally.

The Linux installers have a checksum function too. Some time ago GOG created a broken Big Pharma installer which resulted in a checksum error.

The point is: It is easier if you can check the integrity of an installer without installing the game for backup purposes.

Good point about the back up, but then Gog would just need to provide md5's, we could use any method we want to check it, I used to use them all the time at work, however over the last five years or so the partial or broken downloads on files has gone, since internet improved, so is there much value, I am not convinced. Since I have been using Gog I have had 2-3 failed downloads which the browser mentioned, and one download which didn't work - had to re-download.

MD5's are supplied just not made easily accessible to the gen pop.

gogrepo.py will generate a manifest file with MD5 directly from GOG. It's a python script so running it can be tricky if your not confortable in command line.
