Notes about the GLK 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 GLK file type is primarily associated with 'PaperPort' by ScanSoft Inc.. These DLL-like files (GLK is 16-bit, G32 is 32-bit) are used by ScanSoft's PaperPort to identify supported applications. Examples include PDFLink.g*, which come with Adobe Acrobat Capture.
