What is an E file?
An .E file can be many different things. Most notably, it is an Eiffel Source Code File. The Eiffel programming language was designed by Bertrand Meyer. Other times, an .E file contains EEG medical data for Natus NicoletOne software, or finite element analysis data for Exodus. Because malicious ransomware also uses the .E extension to encrypt victim files, you must be careful when you find an unknown .E file on your computer.
How to open E files?
If your .E file is source code, you can open it with a simple text editor like Notepad++ or an IDE like EiffelStudio. If it is medical data, you need the official medical software. Sometimes, users rename .EXE, .PDF, or .ZIP files to use the .E extension to bypass email filters.
Inspecting with viewer.online
Because the .E extension has multiple possible meanings, we recommend using viewer.online/e to identify the actual format of your file. viewer.online/e can analyze .E files to identify the exact format and creator software, inspect the file structure, extract readable text, and check whether an online preview is available.
Summary
viewer.online/e is useful for identifying, inspecting, and understanding .E files without installing software or dealing with compatibility problems.
