What I mean is when a file name has the "2 input and gate" drawing before the file name, then what I know is it is a symbol file that can be loaded directly to the "sym" directory.?
When a file name has the "NPN bjt transistor" drawing before the file name, then my understanding is it is a schematic file and can be saved under a LTspice schematics folder.
When a file name has the " .lib " after the file name, then my understanding is it is the model simulation file and can be loaded directly into the "sub" directory.?
Bordodynov's file name has ".asy" after it but no "and gate" or "npn" drawing icon before it so I'm not sure where to save that kind of file.
Eric, I think Bordodynov's symbol uses the same technique as one of the two I described.
I'm not sure what you say about the AND gate, because none of these symbols had AND gate icons in them.? In any event, like any other symbol, it can live either in the same directory with the schematic that uses it, or in the Documents\LTspiceXVII\lib\sym directory tree.
