A convenient tree control makes navigating the file system hierarchy a breeze.

All of this is complimented with under-the-hood action history which allows going back and forth between the file system hierarchy.
Built-in drag and drop support enabling copying and/or moving files and folders to different locations.
A special section in the tree navigation of the file dialogs allows adding Favorite locations, so end users can easily navigate their file system.
