How to open 3WD files

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

What is a 3WD file?

3WD files are 3D Construction Kit World data files, which you can read more about below.

The 3WD file extension indicates to your device which app can open the file. However, different apps may use the same file extension for different types of data. So a 3WD opener may not be able to open all kinds of 3WD files. In this case, though, we only know of one specific use.

3D Construction Kit World data

Through our analysis of 3WD files, we know that one use of the format is 3D Construction Kit World data. We have not yet described in detail what these files contain and what they are used for, but our team is working tiredlessly through thousands of file formats. We'd love hearing from you if you have information about the format.

We have not verified any programs yet that works with this specific format. If you know any, please use the 'Suggest a program' link below. Thanks!
