Notes about the QC 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 QC file type is primarily associated with 'Progress' by Progress Software Corporation. The .QC file (along with the .QL file) is generated during the installation of Results. The .QC (and .QL) files may be deleted, and the Results software will recreate them when the program is next started.
