C64 PC64 Emulator file
File type: Emulator file
A 64D file is an emulator-specific file associated with PC64, a Commodore 64 emulator.
The format belongs to the older PC64 software ecosystem and is not a general-purpose file format.

The 64D file extension was reported for use as one of the emulator file types used by the C64 PC64 emulator.
The 64D format is likely a legacy format and is no longer commonly used or broadly supported outside the original emulator.
Open a 64D file with the original PC64 Commodore 64 emulator. Run that legacy emulator on a compatible system, then use its file-opening command to load the file.
There is no generally established converter for the 64D file extension. If the original PC64 emulator provides an export or save-as feature, use it to save the data in another format; renaming the file does not convert it.
