If you go to Import->Batch Import, you will see a checkbox to "Populate metadata from directories". You then need to edit the format string to indicate what field should be updated with each folder depth. If you structure your files like

Base Folder
    Christmas
        Performance1
        Performance2

you could enter a format string such as: %GENRE% / %COLLECTION%

or you could do %COLLECTION% %SOURCE%

it just depends on which fields you want to have populated. Let me know if you need additional information about this.
