What is an AD! File?

Question: What is an AD! File?

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

Before you can open an AD! 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 .AD! file extension refers to.

Answer: A file with the AD! file extension is an OzWin CompuServe file.

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

How To Open an AD! File:

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

As of this writing, I don't have information on any specific applications that will view AD! files or open AD! files for editing. If you know of any, please send me a quick email and let me know the name of the program so I can update this page.

Tip: Use Notepad or another text editor to open the AD! 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 AD! files but it's worth a try.

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

How To Convert an AD! File:

There are two main ways to attempt to convert an AD! file to another file type:

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

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