I use two methods at the same time.
The first is alphabetical the second is a mixutre of genre style and date.
For the first method I have 27 folders: 1 x for numbers ie 0-9, 26 x each letter of the alphabet. I always use the first letter of the artist (excluding The) and any artist I have more than one track from has their own folder, all single track artists just go in the root for that letter.
The second method is mainly for compilation albums or genre specific tracks. I call this folder _Misc (space Misc) so that it appears at the top of my list.
In here I have folders for each decade and folders for general music styles (I have a lot of different styles). So one for dance, one for D&B, then sometimes I break it up within that folder and I’ll have a Ministry and Hed Kandi folders and put all the stuff from each label into it’s own place.
The trick to this is making sure that your files are tagged correctly in the first place.
I use a brilliant little program called Tag & Rename - it’s about $20 and worth every cent.
I’ve used it to do over 10,000 tracks and it’s the only one I’ve found that writes ALL possible tag variants in one go.
When you have spent the time needed to tag your collection properly you will have a very good knowledge of what it is and where it is when it comes to manually looking for things or adding to the collection.
When your tags are done properly, Traktor is VERY good at finding any search you do.
even if you can only remember one part of the tag ie album name or one word from the title, it will find it if you have tagged it properly. you can even search on BPM and mix tracks you would never have thought to mix.
Use an external drive and make sure you back it up VERY frequently (ie weekly) and don’t forget to back up your collection files and stripes too if your using Traktor. It takes my fast PC jsut over 1 week working flat out to re-analyse my collection!!!
I’ve been using this method for nearly 10 years now and I have over 30,000 tracks in my collection all available in an instant once I’ve remember one key fact about the track I want to play. (if you don’t have that key fact your screwed, sorry!)
Best Of luck
when I first decided to go digital I thought it would take me 6 months to do my collection, I’m still doing it!!!
