 You can organize your files by device type, or by function. For example, you may have a folder of "TV" actions, which correspond to Channel Up, Channel Down, Volume Up, Volume Down, etc. Or you may have a "Work Access" folder, which contains files/actions that correspond to Parking Gate, Garage Door, Lobby Entrance.

 ## Sorting and Naming
 The list view is based on the sorted file and folder order. This is enforced by sorting the actual filenames. When there are cases where you need to enforce a sorted order, you can prepend the file and folder names with `XX_` where `X` is a digit between 0-9. This will let you place an action called `On` before `Off`, even though when sorted alphabeticaly, `Off` would come before `On`. Therefore, you would name your files `00_On.rfid` and `01_Off.rfid` - assuming these are RFID saved signals.
