File extension: GRR
File type: Class Roster


Notes about the GRR 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 GRR file type is primarily associated with 'Gradekeeper' by Daniel Ethier. Gradekeeper is a computerized gradebook. You enter grades and attendance and Gradekeeper does the rest: computes grades, prints reports, does seating charts, and even posts grades on-line. With the companion applications for your Palm OS or Pocket PC handheld, you can record grades and attendance during class and synchronize with your desktop computer later.
