The Video Viewing History is a record of all the videos you have viewed.
It includes the date and time spent viewing each video.
This information is displayed when a Video or Topic is selected
in the Contents Tab.

Backup your Video Viewing History to a file. You should do
this frequently to ensure it is not lost due to application errors.
Save the backup file to a location where you can find it. History backup files
will have a kdh extension.
Restore your history from a backup history file. This will
also check for any errors in the backup history file.
Merge a history backup file with your current history. Valid backup history records will be added to your current history if not already there.
Repair invalid history records.
The history works by recording the Topic, Title and File Name of a video.
Topic, Title and File Name information is provided by the Khan Academy, and
may be rearranged or changed by them at any time. You should expect such
changes to occur.
For example, when updating from the Update Tab, the downloaded Topic, Title
or File Name data may have been changed resulting in errors in your History.
If you think your history may have errors, you can easily test and fix it from the
History / Repair menu item.
