Have you ever been creating Revit families, making edits and saving to find your directory looking like this?
This made me think, how can Dynamo help me out?
Enter the File.Delete node.
This node takes a directory as input and a boolean to run it. After running, it shows how many files it deleted. Currently it only deletes files that end with the typical backup suffix in Revit. (Family1.0001.rfa)
