All folders we created so far are "auto-managed"; this means their location is managed by Switch. This makes it very hard to allow users to drop files into such folders as their location might change or might not be accessible to network users.
The solution to this is to create a "user-managed" folder for our drop folder. This will be a folder on the network (or local computer) in a location that we can publish to our other users in the network so that they can drop files in the flow.
A Browse for folder dialog box appears where you can select a folder on your computer or somewhere on the local network (as long as it is accessible from your computer).
You can use this alternative way to create the drop folder: In the Folders pane, browse to the folder you want to use as "Drop Folder". Click on that folder in the Folders pane and drag it onto the canvas. When you drop the folder on the canvas, Switch automatically creates a user-managed folder for you.
