Parameters

Parameter Description

query

Retrieves the reparse point data that is associated with the file or directory identified by the specified handle.

<FileName>

Specifies the full path to the file including the file name and extension, for example C:\documents\filename.txt.

Remarks

  • Reparse points are NTFS file system objects that have a definable attribute that contains user-defined data, and they are used to extend functionality in the input/output (I/O) subsystem.

  • Reparse points are used for directory junction points and volume mount points. They are also used by file system filter drivers to mark certain files as special to that driver.

  • When a program sets a reparse point, it stores this data, plus a reparse tag, which uniquely identifies the data it is storing. When the file system opens a file with a reparse point, it attempts to find the associated file system filter. If the file system filter is found, the filter processes the file as directed by the reparse data. If no file system filter is found, the File open operation fails.

Examples

To retrieve reparse point data associated with C:\Server, type:

fsutil reparsepoint query c:\server

To delete a reparse point from a specified file or directory, use the following format:

fsutil reparsepoint delete c:\server
