Files and folders in ~/Library/Application Support/BetterTouchTool

I see there are several folders and files in ~/Library/Application Support/BetterTouchTool
What are they used for?
Which folders/files can I delete?


Here are the files in Backup and Files folders.


You should not delete the files, they belong to the BTT database. E.g. the BTT clipboard manager does save its data here.

You can delete the backups if you want.
