What Is a DMC File?

Most are probably documents, but there are several possible formats

What to Know

  • Some DMC files are documents that open with Datamartist.
  • Others could be audio files (use FamiTracker) or text files (use a text editor).
  • How you open, edit, or convert your file depends on the format it's in.

This article describes a few formats that use the DMC file extension, including how to open and convert each kind.

What Is a DMC File?

A file with the DMC file extension might be a Datamartist data canvas file, which is a document used to manage datasets from Microsoft Excel, Microsoft SQL Server databases, and others.

Some files that end with .DMC might instead be DPCM audio samples. Often used for video games, they contain audio information for an instrument that a program can then use to manipulate the pitch and other settings.

Other DMC files might instead be Mimic configuration files or Medical Manager DML system compiled scripts.

DMC is also short for a number of technology-related terms, but none of them have anything to do with these file formats. Some examples include digital microcircuit, dial modem connector, dump memory contents, digital media coding, and direct mapped cache.

How to Open a DMC File

Datamartist is responsible for opening documents in that format. Considering that it's a document that references other data, and is saved in an XML-based format, you can also open one with a text editor to read it as a text file.

If you think your file is related to an audio format, you can open it with FamiTracker. This program refers to DMC files as "delta modulated samples."

You can't use the File menu to open a DMC file in FamiTracker. Here's how:

  1. Go to the Instrument > New instrument menu to make a new instrument.

  2. Double-click or double-tap the 00 - New instrument entry that was just built.

  3. Go into the DPCM samples tab.

  4. Use the Load button off to the right to open one or more DMC files.

Other DMC files can be 3D image files used by the DAZ 3D Mimic program for making facial animations.

If it's not in any of those formats, your file could be a script that opens with a program called Sage Medical Manager.

If you find that an application on your PC does try to open the DMC file but it's the wrong program, or you'd rather have another installed program open it, see our guide on how to change file associations in Windows.

How to Convert a DMC File

Datamartist DMC files can't be converted to another file format using that program. However, if for some reason you need it to exist with a different file extension, like TXT, you can use a text editor to do that conversion. Notepad++ is a good choice.

If any of the other formats are able to be converted, there's a good chance the program that opens it is the one capable of doing the conversion.

For example, if you have a DMC file that opens in Mimic, look in that program's File menu for some sort of Save As option. There might even be an Export or Convert button somewhere that lets you save it to a different format.

Still Can't Open the File?

If at this point, your file isn't opening with any of the programs you tried, you might consider that you're misreading the file extension. Some files use a suffix that closely resembles DMC even though the formats are entirely different.

For example, a DCM or DICOM file could easily be confused for a DMC file even though they're used to store medical images—something much different than the formats mentioned on this page.

Another is the DMG format used on Mac computers. If you double-check the file extension and find that you really have a DMG file, follow that link to learn more about that format and how you can open it on your computer.

Otherwise, research the file extension that your file is using, either here on Lifewire or elsewhere on the internet. You should be able to find the format that relates to that file extension and then, ultimately, be able to download the program you need to open or convert it.

DMC is also the name of a textile company whose website is DMC.com. Files downloaded through that website, like these free embroidery designs and cross stitch patterns, are most likely stored in the PDF format (i.e., you can use a free PDF reader to open them).
