You're here because you have a file that has a file extension ending in .dz. Files with the file extension .dz can only be launched by certain applications. It's possible that .dz files are data files rather than documents or media, which means they're not meant to be viewed at all.

The Dzip software is a command line application designed to integrate encoding and compression specifications into files and folders selected for compression by the user of this program. A Dzip file is stored in the DZ format and is appended with the .dz extension. These DZ files can be created and decompressed using the Dzip software. The DZIP compression format is known to be faster in creating a compressed file than other compression formats, and the DZ format may also implement better compression ratios than other compression standards. This means DZ files are compressed in smaller file sizes compared to other compression formats. This is why a DZ file may be included with the DZ application itself in some instances. Digital data compressed and stored as a DZ compressed file can be extracted quicker than other files implemented with other compression specifications and standards. Microsoft Windows users and those with computers running on Linux-based systems can use the Dzip application to create and decompress DZ files. There is also a version of the Dzip software for Mac platforms.

Launch a .dz file, or any other file on your PC, by double-clicking it. If your file associations are set up correctly, the application that's meant to open your .dz file will open it. It's possible you may need to download or purchase the correct application. It's also possible that you have the correct application on your PC, but .dz files aren't yet associated with it. In this case, when you try to open a .dz file, you can tell Windows which application is the correct one for that file. From then on, opening a  .dz file will open the correct application.

Be careful not to rename the extension on .dz files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

A file extension is the set of three or four characters at the end of a filename; in this case, .dz. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
