Non-Kontakt-Player-Libraries (all libraries which are not added to the libraries tab), can be buried in oblivion, since they are not that accessible as those you can find in the libraries tab on the left. For this reason there is the Quick-Load Catalog, which is very very useful especially when you got tons of libraries. This Catalog gives you an even better access to all libraries than the libraries tab since you can categorize and organize all your libraries. And Non-Kontkat-Player-Libraries are no longer being forgotten.
- in Kontakt hit CTRL + F* (or right mouse click** into an empty area of Kontkat) to open the Quick-Load Catalog
- open your Windows Explorer or Finder and navigate to the relevant folder of your instrument.
- drag the relevant nki in the Quick-Load Catalog to favor the Instrument permanently
- create your own folder structure to organize and categorize your instruments.
*) CTRL + F may not work using Kontakt as plugin within a DAW
**) right mouse click also works when you click inside an empty area of a loaded instrument, make sure that you don’t touch any knobs, buttons or other controllable ui elements with your cursor
