The CSO (CISO compressed ISO ) file extension is a compression format used for backing up PlayStation Portable (PSP) gaming titles. It is similar to the widely used ISO (International Organization for Standardization) format but is about 1/5th the size, allowing users to store more content in a smaller file size.
The files are created with the help of software programs such as UltraISO, MagicISO, or Disk Utility. CSO files can be easily converted to ISO or other formats using these programs. More specifically, these programs not only compress ISO images to CSOs, but they can also unpack CSOs back to ISOs. For example, with UltraISO, a CSO file can be decompressed into an ISO file by following the File > Convert > Compressed (CSO, BIN/CUE) Image command from the program menu.
Similar File Extensions
Other compressed file extensions similar to CSO are NDX(Nero Digital Image), IMG(Disk Image), and PAK(Compressed Archive).
Programs for WINDOWS system

After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .CSO) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .CSO extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .CSO file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .CSO extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .CSO extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .CSO file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .CSO file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .CSO file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .CSO file) will be extended to the maximum.
It is also good to check
- if the .CSO file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
