I am trying to find out if there is a way to create a workflow (SPD 2010) for a Document Library that will delete an empty folder from the library if it has been empty for more than a specific number of days. Is that even remotely possible?
I don't see a way to do this with SPD 2010 workflows OOTB, it's certainly possible to build a workflow in Visual Studio and perform these actions. It might be possible using iLoveSharePoint's Codeplex tool, specifically the Get Folder Action. I haven't tried this particular action, but I've used this tool before and it's fantastic. I would give this a shot first, then resort to making a custom workflow if needed.
