Notes about the DOL file extension:
To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened
" (Windows 7) or "How do you want to open this file?
" (Windows 10) if you double-click the file. There click on "More apps"
and choose a suitable software to view such files on your PC or from email attachments.
The DOL file type is primarily associated with 'GameCube' by Nintendo. The Linux kernel for the Nintendo GameCube is commonly built as a DOL file, which is the typical executable file format on this console. Also known as DOLphin.
