Notes about the XADML 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 XADML file type is primarily associated with 'XML-based Application Description Information'. In their simplest form, XADML files provide an XML-structured short description of a single application, saying something like 'This software ideally requires an A1200 with 8 MB of Fast RAM and two floppy disk drives, but it also runs on an ECS system. Insert disk image 1 in drive 0 and disk image 2 in drive 1. The application supports features such as accelerated CPUs and accelerated floppy drives.' Having this information, an application front-end can list the application, the user can click on it, and an Amiga emulator can set up the proper hardware configuration, load the correct ROM and operating system, and then load the application.
