Format description
A compressed form of an ISO image file, compressed ISO (CSO) files are often used in gaming, especially for PlayStation Portable (PSP) games. They work in a similar way as ISO files but because they are compressed, they require less storage space. The drawback is that they could cause loading speeds to be a little bit slower than those of uncompressed ISO files. CSO files can be used on emulators or modded devices that support the format.
Common questions about converting to CSO
Can I convert to CSO in bulk?
Yes, MConverter supports batch converting to CSO. You can even drag and drop folders to convert to CSO. Pasting files and folders copied in the clipboard also works: use Ctrl+V.
Can I convert a file to CSO, if its size is 2 GB?
Yes, with MConverter Pro you can convert big files, up to 2 gigabytes each. The free version lets you convert files up to 100 MB. If you need to convert files over 100 megabytes to CSO, try MConverter Pro. If your files aren’t over 1 GB, then you can use MConverter Plus instead, as it’s cheaper.
