Question: What is an T64 File?

Have you found, downloaded or received an T64 file, but don't know which software program is required to open it?

Before attempting to open an T64 file, you'll need to determine what kind of file you are dealing with and whether it is even possible to open or view the file format.

Answer: Files which are given the .T64 extension are known as Emulator tape image files, however other file types may also use this extension. If you are aware of any additional file formats that use the T64 extension, please let us know.

How to open a T64 file:

The best way to open an T64 file is to simply double-click it and let the default assoisated application open the file. If you are unable to open the file this way, it may be because you do not have the correct application associated with the extension to view or edit the T64 file.

This file format was added to our database by a visitor to this site, but no additional information was provided. We have yet to investigate this file type further, or there was not enough information available at the time to report accurately on the format.

Please check back soon for more information as we are constantly updating our file descriptions based on search frequency.

Tip: Try to open the T64 file using a text-editor such as Notepad, as many file types contain simply contain unformatted plain-text and can viewed correctly using this method.

A .T64 file is a tape image of a Commodore 64 cassette tape. The Commodore 64 was a home computer made by Commodore Business Machines between 1982 and 1994 when the company folded. A device known as a tape drive was released for the machine as a much cheaper alternative to a floppy drive which cost about as much as the computer.

Now days the format is used mostly for older software as most modern C64 software is distributed in D64 files (Commodore 64 floppy disk images).

To open a .T64 file I know of two PC programs which are able to read and edit such files. For Windows there is DirMaster ( and for DOS there is the Star Commander software ( which is also able to transfer data to C64 floppy disks using an original floppy drive and special cable. D64 Editor ( mentions developmental support (not sure if its in the software yet though).

There may be more programs supporting .T64s but those are all I know.

The files may also be used by some Commodore 64 emulators although I know little of these (I like the original hardware).

If you want to make tape images there are two main ways to do it (neither of which I've tried I should add).

You could simply make an audio recording of the tape playing in an audio tape player which would be plugged into your sound card's audio in port. Then you could use the software WAV-PRG ( to convert that to a .T64 file. However if you want improved accuracy in your file you may make an X1531 ( and an original Commodore 1531 "Datasette" tape drive. The software on that site will create a .TAP file, if you really want a .T64, you may need to convert the resulting file or find another piece of software supporting the cable.

I hope this has been helpful.
