Reparse Points and File Operations

Reparse points enable new behavior that you should be aware of when writing applications that manipulate files. For example, backup applications should specify BACKUP_REPARSE_DATA in the WIN32_STREAM_ID structure when backing up files with reparse points. Virus detection applications should search for reparse points that indicate linked files. Most applications should take special actions for files that have been moved to long-term storage, if only to notify the user that it may take a while to retrieve the file.
