To give you a definitive answer, this author tested three games using NTFS folder compression and a community-built "experimental compressed ISO loader" (abandoned since 2021).
You cannot simply drop a .7z file into RPCS3, nor can you enable Windows compression on your game library and expect stability.
If you are running out of space, the best place to regain it is not by compressing games, but by clearing the shader cache. You can delete the cache folder located in rpcs3/dev_hdd0/ to free up space (note: this will cause games to re-compile shaders on the next boot). 3. Using Compressed Formats in Future
If you are having trouble getting a specific game to work, I can help you troubleshoot the error messages or guide you on where to find the official compatibility list.

Highly compressed games with RPCS3, provided they are properly extracted and the files are not corrupt. While they offer a quick way to download games, they often cause issues in the long run. For the best experience, ensure your game dumps are complete before extracting them for use in RPCS3.

user wants a long article on "rpcs3 highly compressed games work". I need to cover technical viability, performance impact, practical methods, file formats (PKG, ISO, folder), challenges, and best practices. I'll search for information. search results cover various aspects: feature requests for compression, performance impact, game formats, space-saving techniques, and emulator features. To gather comprehensive information for the article, I need to open several relevant pages. opened pages provide additional insights. The GitHub issues discuss compression feature requests and potential methods. The forum post mentions mounting DAA images for compression. The other forum post discusses compressed games support and tools like Compactor. The Batocera wiki mentions SquashFS compression. The "Save disk space for ISOs" page notes the lack of direct ISO/compressed file support. I should also look into "rpcs3 iso compression" and "rpcs3 file compression performance". search results provide information for the article. The article will cover: the current state of game compression in RPCS3, why PS3 games are large, the official compressed formats (PKG and disc folder, no direct ISO/CHD support), workarounds for compression (system-level filesystem compression like Windows CompactGUI/LZX and Linux Btrfs/ZFS; mounting compressed disc images; SquashFS for Batocera), potential performance impact, best practices for storage, and a concluding comparison. I will structure the article with an introduction, sections on the lack of built-in compression, official supported formats, practical workarounds (Windows, Linux, disc images, save states), performance considerations, and a summary. Now I will write the article. storage is a universal challenge for emulation enthusiasts, and the PS3 presents unique difficulties. Unlike other consoles that support efficient single-file formats like CHD or RVZ, RPCS3 operates differently. As of now, the emulator lacks —a common feature seen in other emulators.
