Folders give you an easy way to organise your data.
You can create a folder within any of the Explorer entities, but they are probably of greatest use for organising tools and toolpaths.
Create Folder — Select to create a folder called Folder1. You can rename this folder in the normal way, and drag and drop entities of the particular type into the folder (for example, toolpaths into a toolpath folder).
You can create folders within folders, and then drag and drop again:
Each folder has a context menu that enables you to manage the entities in the folder. To display the menu, right-click the folder.
