You double-clicked on a .DMS file, so now you’re seeing the “Choose a program to open the file” message. Of course, you can choose to open the file with a number of programs, but expect the contents to be all garbled. Not to worry, though, we have you covered!
What Is a DMS File?
A Disk Masher (.DMG) image file or .DMG file is a compressed file type that is encoded using specifications similar to that of an Amiga disk image file. It was initially used to archive and compress data on floppy disks.
This file format is copyright-protected. However, it has been pirated widely, so it can be used in various demo scenes in the software development industry. As a result, issues and bugs in the compression algorithm arise.
Before we discuss these issues and bugs, let’s first discuss how to properly open a DMS file.
Pro Tip: Run a dedicated PC optimization tool to get rid of incorrect settings, junk files, harmful apps, and security threats that can cause system issues or slow performance.

How to Solve Issues with DMS Files
Problems with DMS files are almost inevitable. After all, many developers attempt to pirate it, resulting in a confusing algorithm that computers don’t understand.

2. Update the Application or Software You Are Using to Open Compressed Files.
If you have the correct application installed but still cannot open the DMS file, it is likely because you are using an outdated version. Only the latest versions of the software support DMS file formats.
