File & Folder Pairing

By default, most versions of Windows treat .htm files and their corresponding folder as a single entity. Moving or deleting one of the pair to a new location will cause the other to be moved/deleted with it. For example, a web page saved from IE or Firefox will create the corresponding folder of linked images with "_files" appended. If I save a webpage and call it ThaiVisaRules.htm then the paired folder of images will be called ThaiVisaRules_files.

Is there a way to create additional custom pairs like this? Or even file-file pairs? I have a few situations where this would be very helpful. For example, a DJ program I use analyzes each track creates a 'map' of the song beats and places this file in the same folder as the audio file. Analyzing a track named DanceTrack.mp3 will create a file DanceTrack.mxm in the same folder. I'd like to establish a pairing scheme so that when tracks are moved around the .mxm files follow. This would avoid the hassle and wasted time re-scanning the files.

Anyone have any ideas?
