64D file extension - C64 PC64 Emulator file

What is 64d file? How to open 64d files?

File type specification:

Emulator file type icon Emulator file type

The 64D file extension was reported to us for being used for one of the emulator file types for some older C64 PC64 emulator. Most likely legacy format and no longer used.

Help how to open:

This file type is not meant to be opened directly, there is no software that could open and work with it directly, or there is no information available in public sources about opening this file type. This is usually the case of some internal data files, caches, temporary files etc.

How to convert:

As far as we know, this .64d file type can't be converted to any other file format. This is usually the case of system, configuration, temporary, or data files containing data exclusive to only one software and used for its own purposes. Also some proprietary or closed file formats cannot be converted to more common file types in order to protect the intellectual property of the developer, which is for example the case of some DRM-protected multimedia files.
