Understanding CPIO Issues


Issues Opening CPIO Files

Missing 7-Zip

If you attempt to load your CPIO file, you experience a message such as "Can't Open CPIO Files". Generally, this is experienced in %%os%% because 7-Zip isn't installed on your PC. Your operating system cannot associate your CPIO with 7-Zip, so double-clicking the file won't work.


Tip: If you have another software that you know opens CPIO files, you can select it by hitting the "Show Apps" button.


Obsolete Version of 7-Zip

In other instances, your Unix CPIO Archive file version may not be supported by your version of 7-Zip. Installing the latest version of 7-Zip from Igor Pavlov is recommended. This problem is most common when you have an older version of the software application, and your file was created by a newer version that it cannot recognize.


Tip: Sometimes you can get a clue about the version of CPIO file you have by right clicking on the file, then clicking on "Properties" (Windows) or "Get Info" (Mac OSX).


Conclusion: The majority of CPIO file opening issues are due to not having the correct 7-Zip version installed.


Additional CPIO Opening Issues

Even with the correct version of 7-Zip installed, you can still experience difficulties opening CPIOs. Other CPIO opening errors can be created by other system problems inside of %%os%%. Other contributing causes:

  • CPIO file references in the Windows Registry are broken
  • Deletion of the CPIO file description from the Registry by mistake
  • Corrupt install of 7-Zip or other CPIO-related program
  • Your CPIO file is corrupted (issues with your Unix CPIO Archive file itself)
  • Your CPIO has adversely impacted by malware
  • Hardware associated with CPIO has outdated drivers
  • Windows has inadequate resources to open your Unix CPIO Archive file
