The offline answer file should not be opened with a program, instead, upload the offline answer file in DigiExam to the exam it belongs to.
To upload the offline answer file, go to the overview and then find the exam that the offline answer file belongs to, click on the cog-wheel and choose "Upload offline answer file" (see figure 3).
Drag and drop the offline answer file in the crosshatched area (see figure 4) in the box that appears or click inside the crosshatched area to search for the offline answer file on your computers file system. It's possible to add multiple offline answer files at once.
The status off the added offline answer files is shown under the heading "Status" (see figure 5). When all offline answer files have been added, click on the "Upload" button to start the upload.
The status of the offline answer files will change to "Handed in" when the upload is done (see figure 6). Click on the "Done" button in the botton-right corner of the offline answer file box to get back to the last view you were on. If somethin goes wrong with the upload you will receive an error message under the status heading. At the bottom of the article you can see all status error messages and how to solve them.
When an upload fails
Wrong offline answer file
If the upload fails, check if the Exam ID on the offline file matches the Exam ID that the exam has in DigiExam. If it doesn't match you are probably trying to upload an answer to the wrong exam.
Wrong file extension
Check if the file extension is ".dxr", if it isn't there is a chance that its an offline answer file containing an exam and not the answers. If you are unsure, contact the DigiExam support team and they will help you with the offline file.
