Any way to compress game files on linux? I know that all games vary, content vary and so on, but is there any things i can look out for in like an average steam game which I can compress, and the game can still run fine, tools or programs or anything?
The Btrfs and ZFS filesystems support compression.
This is how I do it. I put my Steam directory in an external BTRFS drive with compression turned on. Works great, and allows me to take my library between computers.
Have you measured the difference? Is it huge? I’m curious to understand what the trade-offs are and how many more games can you store on the same drive.
My main goals are efficient space usage and portability, so I’ve never measured anything. I’ll get some stats for you.
I would appreciate even not very accurate comparison just to get the idea. A brief search meanwhile showed me it’s a great idea actually. But having someone who uses that to comment would be great too. Thanks.
I’ll be away for a while, but I’ll get some stats, because now I’m also curious.
No problem, take your time. Feel free to comment on here, or in private, whatever you’re comfortable with.
Turns out that you have to explicitly mount btrfs with the option compress=zstd (or compress=lzo as you prefer) to get any compression done, and I was not doing that. Also, to apply compression to existing data, you have to defragment with compression enabled. Alternatively, you can create a subvolume and set the compression property.
This explains it quite well.
