The disk image files saved from the Commodore 64 (C64) disk takes the default D64 file extension. C64 was a popular Personal Computer system that proliferated in the IT market during the 1980s. This popular file format also supported Game ROM used by the system which includes the 1541, 2031, 3040, and 4040 variants. During the latter part of its existence, the X64 file extension format became the preferred output file for the C64 disk image. The D64 format file also served as an emulator disk file for Commodore systems that included VC and CBM computer system variants. One of the more popular applications to support this file format is the D64 Editor software developed by Forrest Mook. This software can be deployed under the Microsoft Windows Operating System environment. This application is useful in manipulating the contents of the D64 image file and is an extremely light application comparable to the 64Copy program but is distinguished by its ease of use. The program allows the importing and exporting of D64 format file disk images to and from PC hard drive storage devices. It also supports the viewing of the SEQ file formats used by the Commodore text utilizing native C64 font sets. The disk blocks of the D64 file can be manipulated by the Hex editor including the use of directory sorting feature via separators.

The D64 file extension benefits from the move, rename, and display functionalities that allow the exporting of the file to the PRG format.

The BAM as well as the block chain associated with the D64 file can also be viewed by the user with the option of creating blank D64 format files or cleaning existing files. The creation of the file format is supported by the filename builder feature which allows the use of the default C64 character set for image filenames. The data contained in the disk image is encoded prior to storage to the CBM-HD. The D64 file extension are copies of the contents of the Commodore floppy disk placed in another storage media like a USB drive or hard disk. The images can be utilized by emulation programs specifically designed for the Commodore 64 computer system. All of the sectors of the Commodore disk are stored under a single sequential file contained in the disk image. The method of storage is achieved by simply saving the initial 256 bytes of the sector 0 of track 1 followed by the sector 1 and so on. After all of the sectors associated with the first track are stored, the next available track is stored beginning again with sector 0. This process is repeated until all sectors of all tracks are stored in the file using the D64 format.
