Disklavier

Over the past summer I purchased an MX-80 (a 15 year ambition) and
upgraded to XG with a DSR1. Very early on I joined D.U.G. and have not
until now corresponded. My Disklavier is interfaced with my computer
now thanks in large part to research of the archive postings of this
user's group, and now that I've waited out the shipping,
acclimatizing, cabling, software selection/learning curve and or
course, the tuner appointment, I must say I'm absolutely thrilled with
the arrangement. I have moved my 20 store-bought Yamaha albums to the
hard drive for ease of playing and have also, at much time and effort
culled thousands of not-so-hot midi files from the web to about 1500
pretty good arrangements. I have many Vanbasco play lists but do
sometimes want to find a particular selection by criterion other than
alphabetic, and my memory of which sub-directory it may reside, such
as by genre, artist and so on. I have not found in these hallowed
archives or on the net, any type of file utility of the style used for
mp3 music files in which to classify my repertoire. The mp3 utilities,
though designed for music will not recognize the midi file extension.
Windows XP has allowed for additional file information in its
properties but will not allow for easy entry or searching on this. 

I am hoping someone may have blundered upon what has so far eluded me.
Any recommendations? 

Thanks again for this cite and the wealth of knowledge that it holds.
