Opening HD3 files

Did your computer fail to open a HD3 file? We explain what HD3 files are and recommend software that we know can open or convert your HD3 files.

What is a HD3 file?

Every day thousands of users submit information to us about which programs they use to open specific types of files.

While we do not yet have a description of the HD3 file format and what it is normally used for, we do know which programs are known to open these files. See the list of programs recommended by our users below.

We are constantly working on adding more file type descriptions to the site - the current count exceeds thousand by far, and more information about HD3 files will hopefully be added soon.

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
