Reparse Point Restrictions

[This is preliminary documentation and subject to change.]

The following restrictions apply to reparse points.

• Reparse points can be established for a directory, but the directory must be empty. Otherwise, NTFS fails to establish the reparse point. In addition, you cannot create directories or files in directory that contains a reparse point. .
• Reparse points and extended attributes are mutually exclusive. NTFS cannot create a reparse point when the file contains extended attributes, and it cannot create extended attributes on a file that contains a reparse point.
• Reparse point data cannot exceed 16 kilobytes. Setting a reparse point fails if the amount of data to be placed in the reparse point exceeds this limit.
