What Is a DSK File?

Did you find a DSK file on your computer and wonder what program should open it? Maybe someone emailed you a DSK file but you're not sure how to use it. Perhaps you tried to open the DSK file but Windows told you that it could not open it.

Before you can open a DSK file (assuming it's even a file format that's intended to be viewed or edited), you'll need to determine what kind of file the .DSK file extension refers to.

A file with the DSK file extension is a Disk Image file created by various programs for storing images of disks for backup purposes.

Some DSK files may instead be a Borland Project Desktop file or a Simple IDs Database file.

Other types of files may also use the DSK file extension. If you know of any additional file formats that use the .DSK extension, please let me know so I can update this information.

How to Open a DSK File

The easiest way to open a DSK file is to double-click on it and let your PC decide which default application should open the file. If no program opens the DSK file then you probably don't have an application installed that can view and/or edit DSK files.

Warning: Take great care when opening executable file formats received via email or downloaded from websites you're not familiar with. See my List of Executable File Extensions for a listing of file extensions to avoid and why.

 Fortunately, DSK files are not usually a concern.

DSK files that are Disk Image files may be able to be opened with Partition Doctor, WinImage, PowerISO, or R-Studio, though it's unlikely that all DSK files can be opened with each of these programs. It's best to use the same program that created the DSK file to open it again.

DSK files that are Borland Project Desktop files can be opened using Embarcadero Delphi. Simple IDs Database files use DSKE Simple IDs to open DSK files.

If you know of anything else about DSK files, please let me know so I can update this page.

If you find that an application on your PC does try to open the DSK file but it's the wrong application or if you would rather have another installed program open DSK files, see my How To Change the Default Program for a Specific File Extension guide for making that change in Windows.

How to Convert a DSK File

There are two main ways to attempt to convert a DSK file to another file type:

The first option involving opening the DSK file in its native program is preferable because it's both easier and will probably result in a more accurate file conversion. Of course, if you don't have a program that opens DSK files, a third-party file conversion tool (the second option) could be very useful.

Important: You cannot usually change a file extension (like the DSK file extension) to one that your computer recognizes and expect the newly renamed file to be usable.

An actual file format conversion using one of the methods described above must take place in most cases.
