"NFM" comes from "Not File Manager" - a WPF-based hierarchical data manager for windows with:

• modern UI
• flexible layout system
• drag-n-drop-able multitabs interface
• multilingual support (changeable in run-time without restarting app)
• themes support (changeable in run-time without restarting app)

Also application was developed with add-in model in mind and implementation showcase local file system add-in.

Code base was imported from local Perforce v2010 server where I've managed it during somewhere around 2009-2010.
