How to open 3AD files

Did your computer fail to open a 3AD file? We explain what 3AD files are and recommend software that we know can open or convert your 3AD files.

What is a 3AD file?

The 3AD file extension indicates to your device which app can open the file. However, different programs may use the 3AD file type for different types of data.

While we do not yet describe the 3AD file format and its common uses, we do know which programs are known to open these files, as we receive dozens of suggestions from users like yourself every day about specific file types and which programs they use to open them.

We are continually working on adding more file type descriptions to the site, so if you have information about 3AD files that you think will help others, please use the Update Info link below to submit it to us - we'd love to hear from you!
