floppy_drive_0

The option documentation is properly formatted yet

Alias: df0 Example: Lotus2/Disk1.adf

You specify paths for floppy images in floppy_drive_0 through floppy_drive_3. The number of internal floppy drives will be set according to the highest drive number configured.

If the path is a relative path (or just a file name), the file will be looked up relative to [floppies_dir], or to the current working directory.

You can also prefix the path with some predefined prefixes, like $home, $fsuae, $exe, and $config. This file, for instance, will be looked for in the directory containing the FS-UAE executable:

$exe/Disk1.adf

Absolute paths are also supported. Remember that if you use backward slashes () on Windows, you need to double them, for example:

C:\\Amiga\\Disks\\Disk1.adf

Code:

pass
