A. Much of the new Windows 2000 file system enhancements are possible thanks to reparse points which basically provide a “hook” into the file system and allow extensions to the storage subsystem without the need to proprietary code to be written.

Reparse points are actually special file system objects which have a special attribute that activate extra functionality in the storage subsystem. Any file or folder can have a reparse point meaning a single path can trigger multiple portions of extended functionality.
