* KiCad Symbols KiCad symbols are stored in symbol libraries. These symbol libraries ARE NOT directories, they are instead a file with a .kicad_sym extension This file is very easily viewed with a text editor, but do not attempt to create it by hand. The only thing you CAN DO is to rename this file, because the name of the file does not matter. When you add a library to your set of libraries, you give it a "Nickname" and a file, and specify library format "KiCad", and you can also give a description In the manage symbol libraries, you can list the location as either the .kicad_sym file, or the folder holding it. Recommended Approach. Create a new library, for example "MoorTech_Sym". When you create it, you will just give a "directory" as the path location. Use this name as both the nickname and the filename.kicad_sym. You don't have to, but it is simpler Now you can open up existing symbols, or imported symbols, and do a "Save As" into this library. Eventually go back into the symbol library manager, and modify this path to be the .kicad_sym file * KiCad Footprints KiCad footprints are simply single files with the ".kicad_mod" extension. Create a folder anywhere you want named "MoorTech_Foot" Go to the Footprints Library Manager and add this library with nickname "MoorTech_Foot", and set path accordingly Copy any footprints you want into this folder * KiCad 3D models Create a folder anywhere you want named "MoorTech_3D" These are simply step files, and there is no KiCad libary for these. Simply copy these 3D models into this folder and associate them with the Footprint. You set this in the footprint editor, and bring up the propertied menu, and then go to the File-->Footprint Properties-->3D Models Tap and add the .step file here
