### 12.3 Filenames ¶

Symbol names end in `.sym`. The only symbol filename convention that is used in gEDA/gaf is that if there are multiple instances of a symbol with the same name (like a 7400), then a -1, -2, -3, ... -N suffix is added to the end of the filename. Example: `7400-1.sym`, `7400-2.sym`, `7400-3.sym`...

Schematic names end in `.sch`. There used to be a schematic filename convention (adding a -1 .. -N to the end of the basename), but this convention is now obsolete. Schematic filenames can be anything that makes sense to the creator.
