Notes about the DRMX 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 DRMX file type is primarily associated with 'Drumlin' by Drumlin Security. Drumlin provides a secure PDF publishing system for any organization or individual with private or valuable documents to distribute. It provides a free PDF reader/publisher and free PDF writer, together with a central Digital Rights Management (DRM) service. The secured PDF file will typically have a double extension, e.g., FILENAME.PDF.DRM. The locked DRMX file can only be converted to a DRM file using an authorization code.
