What Is a DAR File?

How to Open, Edit, & Convert DAR Files

A file with the DAR file extension is a Disk Archiver Compressed Archive file. Developed to replace TAR, this file serves as a full copy of a group of files and can, therefore, be used to create file backups.

DVD Architect Project files use the DAR file extension, too. These are used by the DVD Architect program to store everything related to a DVD authoring project, like the location of the media files, chapters that should be included in the DVD, and more.

DAR also stands for some other technology terms that are unrelated to a file format, such as direct access restore, data acquisition request, and dual analog route.

How to Open a DAR File

If it's an archive, you can open the file with DAR (Disk ARchive).

If your file is related to a DVD project, use VEGAS DVD Architect.

If you find that an application on your PC does try to open the file but it's the wrong application or you'd rather have another installed program open it, you can change which program opens DAR files by default.

How to Convert a DAR File

There probably aren't many file converters, if any, that can convert a Disk Archive file to another format. Even if you do have access to a DAR converter, know that, much like ZIP, RAR, and similar formats, you can't convert one to anything but another archive format.

For example, even if inside the DAR file is a video like an MP4, which you want to convert to AVI, you can't convert the file directly. You need to first extract the contents out of the archive with Disk ARchive and then convert one of those files to a compatible format (like MP4 to AVI, MP3 to WAV, etc.).

DAR files that are used with DVD Architect are just used by the program to reference other data and describe how the authoring process should work. There aren't any actual files stored inside this kind of file, so it'd be useless to try to convert one to any format other than a text-based format like TXT.

If you need to "convert" the DAR file to a DVD to actually make the DVD use the information stored in the file, first open the DAR file in DVD Architect and then use the File > Make DVD menu item to walk through the process of preparing the DVD files and burning them to the disc.

Still Can't Open the File?

The first thing you should check for if you can't open the file is that the file extension really does read ".DAR" and not something that just looks similar. Because so many file extensions use many of the same letter combinations, it can be easy to confuse them with one another and think that one is a DAR file.

For example, the DAT and DAA file extensions are very similar to this file extension, but if you follow those links you'll see that these formats are not at all related and can't be used with the same programs.

Similarly, the DART file extension is just one letter off of DAR, but it's used for Dart Source Code files, a format that's entirely foreign to the Disk Archive and DVD Architect file formats. DART files open with a program of the same name.
