Some files that end with .DMC might instead be DPCM Sample files. They contain audio information for an instrument that a program can then use to manipulate the pitch and other settings. They're often used in video games. Some DMC files might instead be Mimic Configuration files or Medical Manager DML System Compiled Script files. DMC is also an acronym 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 DMC files that are Datamartist Data Canvas files can be opened with Datamartist. Considering that it's a document file 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 that 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 to do it: Go to the Instrument > New instrument menu to make a new instrument. Double-click or double-tap the 00 - New instrument entry that was just built. Go into the DPCM samples tab. 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, the DMC file could be a Medical Manager Script file that opens with a program called Sage Medical Manager. Take great care when opening executable file formats that you received via email or downloaded from websites you're not familiar with. See our List of Executable File Extensions for a listing of file extensions to avoid and why. In the case of DMC files, Medical Manager Script files should be used cautiously. 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). If you find that an application on your PC does try to open the DMC file but it's the wrong application or if you would rather have another installed program open DMC files, see our How to Change the Default Program for a Specific File Extension guide for making that change in Windows. How to Convert a DMC File Datamartist DMC files cannot be converted to another file format using the Datamartist program. However, if for some reason you need the DMC file 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 DMC formats are able to be converted, there's a good chance that 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 the DMC file 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 file could easily be confused for a DMC file even though it's 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.
