A: It is best not to. Always compress the original ISO file before starting a new game. Converting a save file from an ISO to a CSO is usually fine, but if you experience crashes after converting, revert to the ISO to see if the compression caused the issue.

Ensure you are running a modern version of PCSX2 (Nightly builds are highly recommended). Older stable builds (like 1.6.0) lack native support for certain compression formats. The Verdict
The days of bloated PS2 ISO libraries are over. With the advanced compression support in modern PCSX2 dev builds, you can reduce your collection's storage footprint by without losing any visual or audio quality. For the best balance of compression ratio, performance, and stability, CHD (Compressed Hunks of Data) is the definitive format. It offers superior space savings through LZMA and FLAC compression, consolidates multi-track games into single files, and is fully supported by the emulator.
This is the simplest method for users comfortable with command-line tools.
While these games might technically boot up, they are broken experiences. They frequently freeze during loading screens when the game tries to call up a deleted video file. The Threat of Malware and Scams A command prompt window will open
Single-file formats like CHD replace messy multi-file .bin/.cue formats perfectly.
