Notes about the GRFZ 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 GRFZ file type is primarily associated with 'DPlot' by HydeSoft Computing, LLC. DPlot graphs and manipulates 2D and 3D data from a variety of sources in many different formats. The .GRF format stores 1D, 2D, or 3D graph information. The .GRFZ file is a zlib-compressed version of that file.
