What is a CPIO file?
CPIO is the extension given to files used in UNIX-based operating systems. CPIO are files that are file archives. Technically speaking, CPIO is a type of container that can contain many files. The data in such a container is not compressed. Sometimes they are compressed with Gzip, but then the resulting files get the CPGZ extension.
CPIO archives contain, apart from the actual files, a header file that allows the archive to be restored correctly, eg using the GNU CPIO utility.

How to open CPIO files
If you cannot open the CPIO file on your computer - there may be several reasons. The first and most important reason (the most common) is the lack of a suitable software that supports CPIO among those that are installed on your device.
A very simple way to solve this problem is to find and download the appropriate application. The first part of the task has already been done – the software supporting the CPIO file can be found in the table. Now just download and install the appropriate application.
Possible problems with the CPIO format files
The inability to open and operate the CPIO file does not necessarily mean that you do not have an appropriate software installed on your computer. There may be other problems that also block our ability to operate the Unix CPIO Archive Format file. Below is a list of possible problems.
- Corruption of a CPIO file which is being opened
- Incorrect links to the CPIO file in registry entries.
- Accidental deletion of the description of the CPIO from the Windows registry
- Incomplete installation of an application that supports the CPIO format
- The CPIO file which is being opened is infected with an undesirable malware.
- The computer does not have enough hardware resources to cope with the opening of the CPIO file.
- Drivers of equipment used by the computer to open a CPIO file are out of date.
If you are sure that all of these reasons do not exist in your case (or have already been eliminated), the CPIO file should operate with your programs without any problem. If the problem with the CPIO file has not been solved, it may be due to the fact that in this case there is also another rare problem with the CPIO file. In this case, the only you can do is to ask for assistance of a professional staff.

How to associate the file with an installed software?
If you want to associate a file with a new program (e.g. my-file.CPIO) you have two ways to do it. The first and the easiest one is to right-click on the selected CPIO file. From the drop-down menu select "Choose default program", then click "Browse" and find the desired program. The whole operation must be confirmed by clicking OK. The second and more difficult to do is associate the CPIO file extension to the corresponding software in the Windows Registry.
Is there one way to open unknown files?
Many files contain only simple text data. It is possible that while opening unknown files (e.g. CPIO) with a simple text editor like Windows Notepad will allow us to see some of the data encoded in the file. This method allows you to preview the contents of many files, but probably not in such a structure as a program dedicated to support them.
