How to Reproduce a .CDZ Format

The CDZ file format is a PlayStation disc image that has been further compressed to make the file size smaller. This makes backing up your PlayStation game library less storage-intensive. Several emulators can open the CDZ file format, as well. If you want to reproduce a PlayStation game as a CDZ disc image file, you can do so by following a few steps.

Things You'll Need

ISO disc image file of your PlayStation game

Instructions

- 1
  Visit the pSX emulator website and download the version 1.13 file to your desktop.
- 2
  Double-click the file you saved to your desktop and extract the files to a location you'll remember on your PC.
- 3
  Click the "Start" button and type "cmd" into the search box, then press "Enter." This opens the command prompt.
- 4
  Type "cd" and then the file path of the location you saved the pSX files to. For example, "cd c:\pSX" if you saved the files at c:\pSX. This command opens the pSX directory.
- 5
  Type the following command to convert your PlayStation ISO disc image to the CDZ file format:
  
  cdztool.exe c:\isoimagefile.iso c:\newfilename.cdz
  
  Change "c:\isoimagefile.iso" to the file path of your ISO image file, and change "newfilename" to the name you'd like to give your CDZ file, and then press "Enter." You've successfully reproduced your backed-up PlayStation disc image as a CDZ file.
