IMD format you can gain access to old media if your version of TeleDisk is incompatible with the same version that created the file (a common problem with the TeleDisk format). The precise image format used by TeleDisk is undocumented, whereas the later ImageDisk (.IMD) format is open source. A later variant of the TeleDisk utility is called ImageDisk, which is free to use and is superior to the original. Originally TeleDisk was a shareware program sold by Sydex. It became a standard for people to preserve system (boot) disks for old computers.

This is one of the oldest disk image formats as it was used on other non-DOS computers to create images from mainframes and DEC workstations. IMA file extension, but on occasion this is changed to.

This format is supported by the Windows tool, WinImage, as well as other software utilities.

Raw means there is no header at the start of the file, and no metadata (data that describes the data) stored either. These are dumps of raw floppy disk sectors, usually from 1.44 MB DOS-formatted floppy disks. It creates raw files, so no header or metadata is stored in the imaged file just the contents of each sector on the floppy disk.įor Windows, WinImage can read and write. IMZ, this is a GZIPped version of a floppy disk image, so you would usually need to 'gunzip' the file to extract its compressed contents first.ĭskImage is a DOS utility used to create and restore disk images to and from a single image file in this format. Most raw floppy disk images start with the FAT boot sector. In DOS terms, this will always be the FAT12 file system. IMG file is based on the file system of the disk from which the image was taken. These are not just used for floppy disk images, but also hard disk, optical disks and even bitmap (graphics) images.īecause it's a raw copy of each sector, the actual format of the data held within the. IMG extension are usually raw disk images which contain a sector by sector copy of the original media. Instead, I will summarize the most common types you will see and how best to use them.IMG filesįiles with a. This article will not go into technical detail on the constructs that make up a floppy disk image format.

Floppy drive image file download#

to be able to download a floppy from the web for use on a modern system running a DOS emulator or on an old system with a modern 'floppy drive emulator', such as a Gotek drive. These days we use floppy disk images mostly for two reasons:Ģ) For convenient propagation of a floppy disk's contents, e.g. Floppy disks, as you know, used to be the primary storage mechanism for data in the 80s, and these days both the drives and magnetic media can be problematic to get working reliably. Images of floppy disks have existed since the DOS days, primarily through backup software, often with compression applied to reduce the size of the image file. This means that even the boot sector is contained in the image file, and hence if you restore the image back onto an original floppy disk it would boot just as the original did! It also contains empty sectors if those sectors were empty on the original media. They are called 'images' because typically the file contains a direct 'image' of each sector that existed on the original media. A disk image is simply a single file that contains an entire floppy disk's data.
