Essential KM Files are in the KM Support Folder
- Keyboard Maestro Clipboards.plist
- Keyboard Maestro Clipboard History.plist
- Keyboard Maestro Dictionaries.sqlite
- Keyboard Maestro Macros.plist <---- All Macros stored here
- Keyboard Maestro Variables.sqlite
NOTE: While the KM Support Folder will remain constant for all future (and probably past) versions of Keyboard Maestro, the specific files that KM uses and requires is subject to change at any time.
So if you are doing a backup, it is best to backup the entire folder.
