What is GCZ file?

The GCZ file has been categorized as Game Files. Game Files consists of 1509 similar files. Compressed GameCube/Wii ROM appears on 2 operating systems as a functional file. The file will work on Mac OS, Windows systems, unfortunately not on others. It is recommended to use Dolphin to handle this file. This is a program created by Dolphin Team. There are also 1 alternative programs to handle the GCZ file.

How to open GCZ file?

An often recurring problem with Compressed GameCube/Wii ROM is that GCZ is not associated with the correct program file. Thus, when you open GCZ, the program selection wizard or some other program starts. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the GCZ file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install Dolphin

An often overlooked issue is to make sure that Dolphin is installed on the computer. To do this, enter the name Dolphin into the system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Below you will find a list of applications that support GCZ files.

Programs to open GCZ file

Remember to download programs supporting GCZ files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Dolphin with GCZ files

If, despite the installed application, the GCZ file does not start in the Dolphin application, you must create a file association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. Information about the file and the program that the file is associated with are available here. Changes can be made using the "Change" button. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. The "always use the selected program ..." field will set the Dolphin application as the default for handling the GCZ file.

Step 3. Update Dolphin to the latest version

The fault may also lie with the Dolphin program, it is possible that Compressed GameCube/Wii ROM requires a newer version of the program. This can be done using the application (if it provides such options) or from the Dolphin Team website and install the latest version.

Step 4. Check for the following problems with the GCZ file

The problem may also be with the file itself if the above steps don't work. This could be due to the file itself, the cleanest issues are:

The affected file may be 0 KB or smaller than expected. This suggests truncating the GCZ file contents when downloading or copying. The only repair option is to download the file again.
The most common cause here is computer viruses. Perform a virus scan using available and up-to-date anti-virus software. If this is not possible, you can use the online scanner. For the best results, we will scan the entire operating system, not just our GCZ file. Sometimes virus-infected GCZ files cannot be recovered, so make a backup in advance.
This can happen especially when the program is dynamically developed and the structure of the GCZ files changes over time. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
There can be many reasons for the failure. Depending on the type of file, it is necessary to repair it accordingly. Sometimes the program itself has options to repair the most popular GCZ file corruption. The easiest way to restore the file is from a backup or by contacting N/A, but this one can be expensive. Not all damage can be reversed.
The program indicates that the file is encrypted or corrupted. The encrypted GCZ files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
Some of the system directories are excluded from modification. These directories are write-protected to them and it's very hard to fix this problem. It is best to move GCZ to a different directory.
This problem only occurs with more complex files. Some file types can only be opened in one program at a time. Running programs (including those in the background) should be verified. Sometimes you have to wait for the session to the file GCZ to close. Some anti-virus or backup software may occupy the GCZ file for a certain period of time. If nothing helps, please reset the device.
