How to open COASTS files

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

What is a COASTS file?

COASTS files are AmiAtlas Coasts data files, which you can read more about below.

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