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.

What is an E file?

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.

STK Ephemeris format

Through our analysis of E files, we know that one use of the format is STK Ephemeris format. 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.
