**Mtools** is a [free software](/source/Free_software) [collection of utilities](/source/Utility_software) to allow a [Unix](/source/Unix) operating system to manipulate files on an [MS-DOS](/source/MS-DOS) file system, typically a [floppy disk](/source/Floppy_disk) or floppy disk image.[2][3]

The mtools are part of the [GNU Project](/source/GNU_Project) and are released under the [GNU General Public License](/source/GNU_General_Public_License) (GPL-3.0-or-later).

## Usage

The following refers to mtools usage in floppy images. (Useful for virtual machines such as [QEMU](/source/QEMU) or [VirtualBox](/source/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.[4]
