SPIEFolder - Allows you to either Import a file system folder (And all files and subfolders) into a SharePoint Document Library, and also export a SharePoint Document Library to the file system for
WSS 2.0/SPS2003 or WSS 3.0/MOSS 2007. This tool completely replicates the document libraries folder hierarchy to the file system when exporting, and replicates the folder hierarchy from the file system to the document library when importing.
