In the Options window you can now set up the default path to audio files, video files, image files, and files you have linked to (File Link field):

This means that if you, for example, move your image files to a new drive/folder, you only have to update the path here, and the links will still be valid.

This feature is also useful if you access the same database from different computers if the actual path to the files is different from computer to computer.
