Notes about the PDFENX file extension:
To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened
" (Windows 7) or "How do you want to open this file?
" (Windows 10) if you double-click the file. There click on "More apps"
and choose a suitable software to view such files on your PC or from email attachments.
The PDFENX file type is primarily associated with 'egis' by HiTRUST Inc.. Acer computer users know this program as Acer eDataSecurity. Egis allows users to encrypt both files and folders for data security. A free reader is available for users who need to read encrypted files.
