This isn't very relevant to gaming and should not be suggested as though it is. Compressing your games like this will generally do more harm than good.

I haven't seen any "harm" to come of it yet except for the games I listed earlier in the thread, and I've been using it for a few days now with multiple games, the only thing I see is more space for my hard drive.

It'd be nice to be able to fit an extra major game or two that really benefited from load times on my SSD without dropping it to >50GBs of available space, assuming this doesn't break anything or impact the SSD gains.

I'm looking at you and your long ass load times, Total Warhammer.

I remember using Double Space to compress games back in the terrible dark ages of PC gaming. This almost feels like a throwback. lol

Compressed video recording with LZX:

That's a compression rate of 28.7.

97% space saved.

I'm curious what's the codec for the video since x264, Lagarith, and various lossless codec are already compressed and won't benefit from additional compression.
 
As a native Norwegian reader, let me clarify. Shadow of War does not shrink to from 100GB to 16GB. It is reduced by 16GB, bringing it down to 84GB.

That makes more sense.
I think that means Fortnite must be the most extreme compression so far then, going from 15.7GB to 934MB when using XPRESS16K. They can't be using any compression at all.

Yeah, it's pretty nice, doesn't have an impact on every game, but my SteamLibrary went from 298GB to 215GB.

Some notable examples:
Cosmic Star Heroine: 5GB -> 2GB
God Eater 2: 14 GB -> 5 GB
Overgrowth: 16 GB -> 7GB
Pillars of Eternity: 14GB -> 8GB
 
this seems really interesting for my ripped games "archive"
Going to have to try it out

Edit: My prince of persia forgotten sands disc rip went from 4,07GB to 56,6MB. That's pretty crazy, this will save a lot of size for disc archiving at the very least

I've been using NTFS compression for almost 2 years and never had any problems with it. The only thing stopping me from using the more sophisticated compression algorithms was the integration with windows. Back then new/updated files were not automatically compressed and I didn't like having to manually run a cli command for recompression from time to time because of this.

Yeah, my bad. Was a bit tired when making the post.

The author has made another post on the Win10 subreddit, with a couple interesting stats: https://www.reddit.com/r/Windows10/comments/77scky/its_been_barely_a_week_since_i_posted_my/

Cuphead seems to handle compression really well, went from 11GB to 2.75GB. I wonder if this could be used to deliver games through Steam and the Win10 Store. If they could be downloaded heavily compressed as this and then unpacked on the HDD after, it would be great for people with datacaps.

It would be great if content delivery had that level of compression. An hour decompressing data would be far more beneficial than downloading for several more.

Thanks for the heads up, OP! I don't have any issues with storage, but it's always nice to have more free space in your disks :)

Also, holy shit, Cuphead. Compress your stuff, devs! From 11 GB to 2 GB...

I compressed my steam folder (more than 2TB) and saved 336 MB lol...

Are you sure you picked the recursive compression? Meaning that it also compress folders within the folders you picked, not just the contents of the folder you chose.

Otherwise, you have 2 TB of games that are already perfectly compressed by default... and I honestly doubt that, knowing devs these days :p

There's nothing particularly spectacular about the compression algorithms used, the advantage is largely that it's native and transparent to the applications, so you can use it for anything.

For comparison just tried compressing my Cuphead folder with default 7zip, and it came out at 1.84GB.

I wouldn't suggest to do that. I compressed my hdd to save space due to games and the result was that it was insanely fragmented. Loading times got so bad I had to format my hdd drive completely. Ever since then I am never compressing games again. Don't do it, it isn't worth it.

this is how bad it got

There needs to be a space saving app that just compresses useless shit in games like FMV while leaving the game data proper untouched. Max Payne 3 was a shocker for that.
 
Beware: with Ghost Recon Wildlands, any patch that you install after having the folder compressed, breaks the game. There's no turning back after that, only way is to redownload.

This tool is great, but it can lead to some issues.

Good point on fragmentation as it will affect speed on spinning disk. However if you have an SSD then it doesn't matter.

How do you know it was caused by this? What does the built-in Windows Defrag tool tell you about the fragmentation? Lots of third party tools unnecessarily (According to MS themselves) defrag files larger than 64mb, which the built-in defrag skips. Might not be as bad as you think.

Some time back i ran Defraggler and it told me i had some heavy fragmentation even though Windows 10 reported a very low number. Large files are simply unneccesary to defragment.

As you see 2 different programs told me the same and I actually used another program but don't have a picture. Also after formatting my hdd drive due to excessive fragmentation, I again compressed a game to see and it got instantly fragmented. And if it wasn't as bad as I thought then why were loading times so bad? Yes the built in MS defrag tool didn't say things were that bad but trust me I could feel they were bad.

No problem with the NTFS compression and Wildlands. But still strange since the compression should be transparent for the applications regardless of which one you are using.

Wondering why some games may break under this, I guess compression does not work so transparently with mmap like APIs or something.

Both those programs will report files larger than 64mb as fragmented if they are. The reason loading times were bad might be because of the compression algorithm. Did you use the same as the one linked in the original post? If so, perhaps performance is an issue with certain games. Doubt it was because of the fragmentation though, if Windows told you everything was fine.

Its relevant because its proves that many developers don't bother with compression, and that is a terrible practice.

It's seems some developer blow up the game size on purpose, because some of the uninformed gamers think that big game sizes are a sign of quality.

Yes, but certainly not on this level.

On a better level.

Slayaway Camp (also an Unity title): 257 MB on disk, 75.3 MB with XPRESS16K, 46.1 MB Steam download.
Shadowrun: Hong Kong: 8.95 GB on disk, 3.38 GB with XPRESS16, 2.4 GB Steam download.

And if you compare more recent big releases? Cuphead, Shadow of War and Evil Within 1 and 2 all seem to benefit a lot from this.

I'm not saying Compact doesn't compress things. I'm just saying whatever Compact does, SteamCDN does better. Mainly due to the fact that it's not a runtime compression.

(Don't have any of the titles you mention, but Cuphead is a Unity title, and should behave exactly as the two games I mentioned).

Just means the devs didn't even bother to use lossless compression.
I guess you could argue that it reduces CPU load.

Titanfall 1 was something like 50GB on PC because the devs left everything uncompressed in order to free up CPU power for low-end users.
