Open D64 File

D64 files are disk image files, created from a Commodore 64.

The Commodores were the most popular personal computers at the time, becoming one of the most important companies in those years.

Commodore made the most popular and best-selling desktop computer in the world, the Commodore 64.

Thanks to the success of 64, Commodore continued to manufacture more home computers, including new versions of the more powerful Commodore 64, such as the Commodore 128 or the Commodore 65 that finally did not see the light of day.

What is a disk image?

A disk image is a complete, sector-by-sector copy of everything on your computer or external drive, completely retaining all the files on your system and faithfully reproducing all your data.

With a full image backup, you protect everything, including boot information, operating system, settings, and data.

In this case, the D64 file is the image that is created by backing up data from a Commodore 64.

To use a D64 file, it is necessary to have a Commodore 64 hardware, or at most, an emulator like the ones you will see below:

CCS64

CCS64 is an emulator software for PC, designed specifically for Commodore 64 and also in the future for other platforms.

It was developed by Hakan Sundell in 1995 and has been greatly expanded since.

Hoxs64

Hoxs64 is another Commodore 64 emulator, specially developed for Microsoft Windows 10.

This emulator is characterized by substantially reproducing the Commodore 64, which is a legacy machine, in detail.

DirMaster

DirMaster is a Windows compatible user interface application designed for browsing and managing collections of disk images, very common in the Commodore enthusiast community.

DirMaster, in particular, supports common emulator disk image formats like D64, D81, and D2M, and almost all native Commodore file formats like ARC, SDA, INX.

It is also capable of handling graphic formats.

DirMaster was designed to provide users with a perfect combination of familiar appearance, feel and manageability.

D64 files are binary and should not be attempted to be opened manually, by the user.
