My workflow consists of a single "in progress" folder and a system of project based archival folders. This system works quite well for me, I always know where the documents I am working on are. However I work in a lab and therefore work at multiple networked instruments throughout the day. My "in progress" folder contains way to many important files to leave network access open to it. So, to help organise this chaos I use a network accessible public folder on my computer as a drop point. I then use Synctoy to sync files from here to my "in progress" folder.
Synctoy is a great little piece of software and it is free from Microsoft. It allows you to link any two folders on your PC and have them sync in one of three ways.
Synchronize - sync's both ways including both renames and deletes
Echo - sync's one way includes both renames and deletes
Contribute - sync one way includes renames but not deletes, this is the one I use for my drop folder.
I highly recommend Synctoy, give it a try.
