Egis encrypted HTML file
File type: Encoded and encrypted file
The .htmlenx file extension identifies an encrypted HTML file created by Egis for Microsoft Windows.
The file contains HTML data protected by Egis and is intended to be handled by Egis rather than opened directly in a web browser.

Egis uses the .htmlenx file format for HTML content that has been encrypted for protection. The encryption prevents the contents from being read as ordinary HTML without the appropriate Egis access or decryption process.
An HTMLENX file is therefore an Egis security file, not a standard web page. It belongs to the Egis software environment on Microsoft Windows and may need to be decrypted before its HTML content can be viewed or used by another application.
Open the .htmlenx file with Egis on Microsoft Windows. Use Egis to access or decrypt the file; a web browser or text editor cannot normally read its protected contents.
If Egis does not open the file automatically, start Egis first and use its file-opening or decryption function, if available.
The file must first be decrypted or exported with Egis.
After the contents have been recovered as ordinary HTML, they can be saved or converted using a suitable HTML editor or web-development tool.
