The mb2 file extension is associated with McMyAdmin, a web control panel and administration console for Minecraft servers developed by CubeCoders and available on multiple platforms.
A typical mb2 file contains backup data for McMyAdmin. It is a ZIP archive with the .mb2 extension, rather than the usual .zip extension, so that McMyAdmin can identify it as one of its backup archives.
McMyAdmin can use an mb2 file as a backup through its backup or restore functions. To inspect the contents manually, rename the file with a .zip extension or open it with an archive utility that supports ZIP files.
The file can be extracted on any platform with a compatible compression tool, but extracting it does not by itself restore the backup in McMyAdmin.
An mb2 file does not normally need conversion. Because it is a renamed ZIP archive, changing its extension to .zip makes it suitable for standard ZIP tools, and changing it back to .mb2 restores the McMyAdmin backup filename.
For an actual backup restoration, use McMyAdmin rather than converting the archive to another format.
