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

E files are STK Ephemeris format files, which you can read more about below.
The E 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 an E opener may not be able to open all kinds of E files. In this case, though, we only know of one specific use.
