Folder2Junction moves a folder to a new location, then makes a NTFS junction in the folder's original location pointing to its new location. NTFS junctions are like wormholes in the file system. Folder2Junction was created so that it would be easier to move sensitive files to an encrypted disk (for example, using TrueCrypt) while keeping junctions in the files' original unencrypted location to maintain ease-of-access and compatibility with applications.
