How to open GRR file?

The main problem with Gradekeeper Class Roster Format is that the GRR file is incorrectly associated with programs. Thus, when you open GRR, the program selection wizard or some other program starts. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the GRR file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install Gradekeeper

In this case, you should first verify that the Gradekeeper application is installed on the computer. This can be achieved by typing Gradekeeper into the operating system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Below you will find a list of applications that support GRR files.

Programs to open GRR file

Remember to download programs supporting GRR files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Gradekeeper with GRR files

If the application is or has been freshly installed, but the GRR file still does not use the Gradekeeper program, it means no association. This option is available from the level of Properties of a specific file available in the context menu. The displayed window will contain information about the program that supports this type of file. Changes can be made using the "Change" button. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. Checking the "Always use the selected program ..." box will permanently associate the GRR file with the Gradekeeper program.

Step 3. Update Gradekeeper to the latest version

If, however, after binding Gradekeeper with Gradekeeper Class Roster Format there were still problems, you should update the program to the latest version. In this case, use the Daniel Ethier website or update the program from the application.

Step 4. Check for the following problems with the GRR file

Of course, it may happen that despite the above steps, the file still does not work. This could be due to the file itself, the cleanest issues are:

The affected file may be 0 KB or smaller than expected. Usually this applies to GRR files downloaded from the Internet in case the download did not finish properly. Downloading the file again should fix the problem.
The most common cause here is computer viruses. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Alternatively, you can use the scanners available online. For the best results, we will scan the entire operating system, not just our GRR file. As a result of the scan, sometimes it is not possible to recover GRR files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
A typical compatibility error - the program does not support the older version of the GRR file. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
There can be many reasons for the failure. Repairing is very dependent on the file type. Some programs offer the option of recovering data from damaged GRR files. The easiest way to restore the file is from a backup or by contacting Gradekeeper, but this one can be expensive. Not all damage can be reversed.
The program can also signal the fact of encryption. The encrypted GRR files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. These directories are write-protected to them and it's very hard to fix this problem. If possible, you can try to move the GRR file to another location.
This problem only occurs with more complex files. In this case, the GRR file is blocked by the first application to open it. Just close unnecessary programs. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the GRR file for a certain period of time. If nothing helps, please reset the device.
