What is a WBFS file?

WBFS files mostly belong to Wiimms WBFS Tool by Wiims WBFS Tool Developers. A WBFS file contains the disk image of a Nintendo Wii video game disc cloned by third-party tools like Wiimms WBFS Tool (also called WBFS Manager) and other Wii programs. WBFS files make it possible to save the backups of Wii game discs on different file systems instead of relying solely on Waninkoko's USB Loader utility. Dolphin and other Wii console emulators can mount and run game backups saved in WBFS files.

How to open WBFS files

You need a suitable software like Wiimms WBFS Tool from Wiims WBFS Tool Developers to open a WBFS file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your WBFS file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a WBFS file directly in the browser:.

WBFS file format:

If you can determine the file format, the associated program can also be determined. The initial characters of a file are called signature, sometimes also referred to as "magic bytes". The signature can be used to infer the file format. File extension, signature and file format must match; otherwise errors will occur when the file is opened. So you need a detailed analysis of a file to find out the format and the associated program. In the following you will find our evaluation of the WBFS files:
