Any way that makes sense to you-- by emulated keyboard type (i.e. Moog, Arp, OBX, DX7, organ, electric piano, etc.), or by function (leads, pads, sfx, rhythm, "plucks," etc.), or by main waveform associated with your patch (square waves, sine waves, triangular, sawtooth, pulse)... Give them names based on what they sound like to you, or just abstract associations, then put those in alphabetical order. Or by date created. However is easiest for you to remember and access later when needed.

Hi Olie ,
After some time I came to this: Basses, Synth FX, Pads (no matter Leads are there too, everything sustained) and iirc Plucks. So it's 4 folders, no matter how weird name of the patch is - it's in the folder. Works for me
I'd just go the tagging route, instead of having to force them to be one thing but not the other. So instead of deciding whether it's "strings" or "pad", you tag it both with "strings" and "pads".
