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

Before you can open a DAR 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 .DAR file extension refers to.

A file with the DAR file extension is a Disk Archiver Compressed Archive file.

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

How To Open a DAR File

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

DAR files can be opened with DAR (Disk Archive). Select the latest version link at the top of the download page to ensure you get the up-to-date revision.

Tip: Use Notepad or another text editor to open the DAR file. Many files are text-only files meaning no matter the file extension, a text editor may be able to properly display the file's contents. This may or may not be the case with DAR files but it's worth a try.

If you find that an application on your PC does try to open the DAR file but it's the wrong application or if you would rather have another installed program open DAR 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 DAR File

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

The first option involving opening the DAR 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 DAR files, a third-party file conversion tool (the second option) could be very useful.

Important: You cannot usually change a file extension (like the DAR 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.
