Which drive imaging utility creates files with the extensions 'dig' and 'bt'?

I have a drive image which I made with a freeware disk imaging uitility in 2005. I can't remember which utility it was. I have 2 files with extensions 'dig' - 55GB and 'bt' - 1 kB. The file with the 'bt' extension is not text and has a lot of nulls with the size of the drive. I've googled for these extensions but have been unsuccessful.

Can someone please point me to which utility was used to create this image?

I think you're basically out of luck in terms of being able to restore that image unless you can find a copy of the utility you used in your own backups.

The .DIG extension is used by a couple of audio processing programs, and by some text processing utilities.   Here's the most comprehensive list I could find from a single source:  http://file-extension.net/seeker/file_extension_dig

The .BT extension is used by a terrain mapping application (VTBuilder) and little else.   [http://file-extension.net/seeker/file_extension_bt ]

Clearly whatever you used to image the system 3 years ago is not a well-known imager and may or may not even still be available.   I'd search through your personal archives to see if you saved a copy of the utility ... that's probably the only way you'll be able to restore the image.   It's always a good idea to keep the program you create an image with together with the image -- even major imaging products sometimes make format changes that can be troublesome when trying to restore older images; so having access to the actual version you used to create the image is an excellent idea.

Glad you found it ... as I said above,   "... I'd search through your personal archives to see if you saved a copy of the utility ... that's probably the only way you'll be able to restore the image."

I do, however, think that was a good answer, so I object to closing the question without acknowledging any credit for that comment.

I'm supposed to give credit for a comment about looking through my archives? Of course, I looked through my archives, before even posting the question. And I did not have a copy of the utility.I found the answer with someone else's help who knew which application the extension belonged to.
