What is an ADD file?

The .ADD file extension is used by many different software applications to store varied data. Because the extension is shared, an .ADD file might contain database information, application settings, or system documentation. The most common uses include Advantage Data Dictionary files used by Advantage Database Server, Dynamics AX Developer Documentation Files created by Microsoft, and Address Book files created by older software like Corel WordPerfect. Other systems use .ADD files for CAD software add-ons in Allplan, video recordings from American Dynamics Intellex DVRs, or even compressed game data archives.

How to open ADD files?

You must use the correct software to open an .ADD file properly. If the file is a database dictionary, you need Advantage Database Server. If the file contains developer documentation, you need Microsoft Dynamics AX. Because you cannot easily tell what type of data your file contains just by looking at the extension, opening it on your desktop can be difficult. Your operating system may display an error or attempt to open the file in the wrong program.

Best practices and troubleshooting

Do not rename the .ADD file extension. Renaming does not convert the file format and will not make it open in a different program. If you are unsure what your file is, viewer.online/add can analyze .ADD files to identify the exact format and creator software, inspect the file structure, extract readable text, and check whether an online preview is available.

Summary

Because .ADD has multiple possible meanings, we recommend using viewer.online/add to identify the actual format of your file. viewer.online/add is useful for identifying, inspecting, and understanding .ADD files without installing software or dealing with compatibility problems.

There are many types of .ADD files. Because the .ADD extension is used by Microsoft, SAP, Corel, and other companies, your computer may not know which application to use.

It depends on the specific file type. Some .ADD files contain plain text or XML, while others, like American Dynamics Intellex DVR video files or compressed game archives, are strictly binary data.
