How to open DC1 files

Did your computer fail to open a DC1 file? We explain what DC1 files are and recommend software that we know can open or convert your files.

What is a DC1 file?

DC1 files are DuneGraph Compressed bitmap files, which you can read more about below.

The DC1 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 DC1 opener may not be able to open all kinds of DC1 files. In this case, though, we only know of one specific use.
