The mtools are part of the GNU Project and are released under the GNU General Public License (GPL-3.0-or-later).


The following refers to mtools usage in floppy images. (Useful for virtual machines such as QEMU or VirtualBox.)

Copying a file to floppy image:

$ mcopy -i Disk.img file_source ::file_target

Copying a file from floppy image to the current directory:

$ mcopy -i Disk.img ::file_source file_target

Deleting all files in the disk image

$ mdel -i Disk.img ::*.*

The drive character : (colon) has a special meaning. It is used to access image files which are directly specified on the command line using the -i options.[3]
