What is a DIZ File?

Question: What is a DIZ File?

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

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

Answer: A file with the DIZ file extension is a Description In Zip file.

DIZ files of this format are found within ZIP files, usually in the form of FILE_ID.DIZ, and contain information about the other files contained in ZIP file.

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

How To Open a DIZ File

DIZ files are text-only files so any text editor, like Notepad in Windows, will be able to properly display the file's contents.

Usually, the easiest way to open any file is to double-click on it and let your PC decide which default application should open the file. If no program opens the file then you probably don't have an application installed that can view and/or edit it. DIZ files are a little different though. While no program probably associates a DIZ file with a particular program, they are just simple text files so like I said above, just open any text editor first and then browse to the DIZ file you want to view.

If you know anything else useful about DIZ 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 DIZ file but it's the wrong application or if you would rather have another installed program open DIZ 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 DIZ File

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

The first option involving opening the DIZ file in its native program is preferable because it's both easier and will probably result in a more accurate file conversion. Neither of these options apply well to DIZ files since they're just text files, but if you have a DIZ file that might be of another format, "converting" the file might be something you're after so those tips might help.

Important: You cannot usually change a file extension to one that your computer recognizes and expect the newly renamed file to be usable. An actual file format conversion is usually necessary. However, since a DIZ file is just a text file, you could rename FILE_ID.DIZ to FILE_ID.TXT and it would open just fine.
