Opening DEC files

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

What is a DEC file?

Files with the .dec extension are most commonly associated with declaration files. The DEC files are text-based declaration files that are used by a variety of Application Development Language programs. They contain the constants and variables that are referenced by other files within the associated programming project.

The .dec file extension is also used for DEC DX WPS Plus document files, decoded files, Dolphin EasyConverter project files and Magic: The Gathering deck of cards files.

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.
