Line 1: Mtools is a collection of tools to allow Unix systems to manipulate MS-DOS based filesystems, such as [[FAT]]. It provides command-line utilities to read, write, and move files on an MS-DOS filesystem. Mtools is not capable of facilitating mounting an MS-DOS disk image to the host system. One common use for Mtools is to copy files to a FAT disk image located on the host system. MTools gives you command line access to a disk image, it does not mount an image like the other programs, but you get MTools 'dir', 'format' etc that access the image. This is obviously not as integrated as mounting the image so the Host OS itself can see the filesystem, but its the next best thing. Mtools is available in the package repositories of most Linux distributions, or can be built from source under [[Cygwin]]. The source code is available here: https://www.gnu.org/software/mtools/ ==Using disk images== The <tt>-i</tt> option, followed by a disk images file name, allows for using a disk image in place of a real device when the drive letter <tt>:</tt> is used. For example to copy the file <tt>kernel.elf</tt> from the working directory to the root directory of the image <tt>floppy.img</tt> one would use mcopy -i floppy.img kernel.elf ::/ It is important to notice that, while MTools claims to include only the minimal BIOS Parameter Block (BPB), it actually uses the FAT16 extension (see e.g. [http://www.win.tue.nl/~aeb/linux/fs/fat/fat-1.html] under 'FAT16' for an explanation) to the BPB if you format a FAT12 image. ==See Also== ===External Links=== * https://www.gnu.org/software/mtools/ Mtools home page. * https://linux.die.net/man/1/mtools Mtools Linux man entry. {{Stub}} [[Category:Disk Image Utilities]]
