  • Marvel's Guardians of the Galaxy "We wanted to give you an update on the final size of the PC version of the game, which will not be 150 GB. The team is in the last stages of optimizing the final game and we can confirm the file size will be approximately 80 GB at launch." | 2021-10-20
    Compactor shaved 30% off my DCS install - 80GB instead of 114GB.
  • File compression using ‘CompactGUI’? | 2021-10-16
    That's simply not true. I use compact.exe to compress all my games, its NTFS' built-in seamless compression. If you're going to give advice to someone at least make sure you know WTF you are talking about. u/Yes_This_Is_A_User use this one it's a nicer UI.
  • Help me I need Storage!!!! | 2021-10-01
    Hey, i’ve used a program called Freaky/Compacter,, it worked really well for me, got 10gbps off cs go, but it doesn’t work with all games, on gta i got around 800mbps, you should give it a try, it’s a life saver!
  • how bad is it to play games of internal SSD with linux OS runnig of USB
    You can free up a considerable amount of space in Windows by deleting junk files and old windows updates. Run cleanmgr as administrator first (tick all the boxes), reboot and then download and run ccleaner. Further to that, you can seriously free up a ton of space by compressing your games library and program files folders - you can use Compactor for this.

    The tool in the image is Compactor, a GUI front end to the Windows compact.exe built-in tool to utilise NTFS filesystem compression.

    Compactor (GUI for built-in win 10 transparent compression) works really well for games, often getting 0.30x-0.65x compression ratios, game updates only decompress and patch what they need and then you just have to rerun the tool to recompress them. depending on your CPU, some games even load faster.

    Try out Compact GUI. select the steam game folder and let it compress all the repeated data

  • NTFS compression is still a single core task in 2021, unfortunately. It's all about priorities, seems the 10th UI redesign for the next Windows was more important... | 2021-09-06
    There's even a GUI if the command line scares you: | 2021-09-06
  • ARK's filesystem is atrocious and a fix is long overdue | 2021-09-04
    Most of the files are uncompressed. If you compress them yourself with a program like windows' compact.exe using CompactGUI, you can get ~50% storage savings (but steam will redownload affected files any time it tries to verify files, like after an update). If you try this with other games, the results are almost always much lower (Arma 3 has ~12% savings, Marvel's Avengers has 0%, Call of Duty Modern Warfare is ~6%). The performance and loading impact of doing so is minimal, and may even improve performance for older games as smaller files will load into RAM faster.
  • Ark installation size? | 2021-08-31
    Ark's use of Unreal engine libraries is notoriously bad. You can use CompactGUI to reduce the size significantly without much impact on performance:

    To free up space on HD, basically, I making some research now, CompressGui has a variety of games that can be compressed:

    You can compress the ark folder with this:
  • The "Size on Disk" shelf filter for display in the Steam library doesn`t actually display the games listed according to their actual size on disk but rather their whole size in actual. | 2021-08-15
    Here’s a great tool in case you want to use it yourself.
  • Is there a way to compress the 71 GB assets folder?
    You may get some easy compression done using the Windows filesystem compression tools (e.g. use CompactGUI), but don't expect too much. The larger files are most likely already compressed (textures, sounds, etc) and you won't gain much by compressing them again.
