What is MI4 file?

The file with the extension MI4 is the System Files file type. The author of this format is NVIDIA. System Files consists of 323 similar files. Audio Player Firmware Format appears on 3 operating systems as a functional file. These systems consist of Linux, Mac OS, Windows, although it may occasionally be found on another system, it will be non-functional. The Rockbox application is recommended to open the file. It was released by The Rockbox Crew. This file type can also be opened by 2 other programs.

How to open MI4 file?

The most common problem when using Audio Player Firmware Format is that a specific MI4 is not associated with the program. This is manifested by the fact that MI4 files open in unusual applications or do not have an assigned program. How to solve such a problem?

The first thing you should do is just "doubleclick" on the MI4 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 Rockbox

The first step is to check if the computer has the Rockbox program installed. This can be achieved by typing Rockbox into the operating system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file MI4 with Rockbox. Below is a list of programs that support the file MI4.

Programs to open MI4 file

Remember to download programs supporting MI4 files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Rockbox with MI4 files

If, despite the installed application, the MI4 file does not start in the Rockbox application, you must create a file association. It is most convenient to call the context menu with the right mouse button and select Properties. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Using the "Change" button we can set the program to handle this type. 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 Rockbox application as the default for handling the MI4 file.

Step 3. Update Rockbox to the latest version

If, despite the association of the Rockbox program with the Audio Player Firmware Format file, the file still does not open, check the program version and possibly update it to the newest version. This can be done using the application (if it provides such options) or from the The Rockbox Crew website and install the latest version.

Step 4. Check for the following problems with the MI4 file

If the above steps do not help, you can assume that the file itself is not correct. This could be due to the file itself, the cleanest issues are:

Very often, the file may be size 0 or incomplete. This suggests truncating the MI4 file contents when downloading or copying. The file should be downloaded again, making sure that the process has finished correctly.
The operating system may be infected with a computer virus. A virus scan using an up-to-date antivirus program should fix the problem. If this is not possible, you can use the online scanner. The scan should cover the entire computer, not only the MI4 file that we want to open. As a result of the scan, sometimes it is not possible to recover MI4 files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
This can happen especially when the program is dynamically developed and the structure of the MI4 files changes over time. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for this. The repair method must be adapted to the type of file and damage. Sometimes the program itself has options to repair the most popular MI4 file corruption. The easiest way to restore the file is from a backup or by contacting NVIDIA, but this one can be expensive. Not all damage can be reversed.
The program can also signal the fact of encryption. The encrypted MI4 files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. These directories are write-protected to them and it's very hard to fix this problem. If possible, you can try to move the MI4 file to another location.
This problem only occurs with more complex files. You may find that another program you are using is preventing you from working with the file. Just close unnecessary programs. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the MI4 file for a certain period of time. If the problem persists, restart the machine.
