Windows 2000 supports the use of Directory Junction points and Volume MountPoints to graft the namespaces of other volumes under folders contained onNTFS-formatted partitions. You can use this functionality to gain access toand store data on alternate volumes without having to address them using aseparate drive letter.

Windows Explorer, along with tools such as Chkdsk.exe, do not traverse NTFSJunction/Mount points, but instead show real statistics associated with theactual physical volume.
To acquire real statistics about available and total disk space associatedwith a given namespace (such as C:) that contains Junction/Mount points,list the directory for the root of the host drive. For example:
dir c:\ /s
This command traverses the Junction/Mount points and provides accuratestatistics for the drive C namespace.

For Volume Mount points, you can also right-click the folder hosting thealternate volume, click Properties to reveal the statistics for the mountedvolume, then add it to the statistics of the host volume.


Drive C is a 2-gigabyte (GB) drive and shows 500 megabytes (MB) free inWindows Explorer. C:\Volume2 is a Volume Mount Point to another 1-GB drivethat has 800 MB free space.

The properties of the C:\Volume2 folder reveal the statistics of theunderlying Volume of 1 GB total space with 800 MB free space which you canadd to the statistics of drive C.

The "dir C:\ /s" command shows 3 GB total space with 1.3 GB free.
