… for more information about reparse points, junction points, volume mount points, symbolic links on NTFS drive (“reparse points” is the generic term for all of them) led me to write a tool called looklink. I put it into the PUBLIC DOMAIN in order to allow others to make use of the CReparsePoint class. The (obsolete as of 2010-01-27)CSimpleBuf class was merely used for convenience, but could be easily replaced by new/delete[] or any other approach.
The tool itself may only be of limited use to the average user, but it allows to get some insight into the innards of reparse points, although the exposed feature set is relatively limited. The class itself, however, allows for a little more …

Updated the project and the CReparsePoint class. It does now handle the volume mount point detection properly, even though this does not mean it is located in the list kept in the NTFS attributes.
I’ll very likely add the ability to create and modify symlinks as well 😉

Added a member function to return the status of the FILE_ATTRIBUTE_VIRTUAL bit.

CReparsePoint now owns a much simpler rewrite of the CSimpleBuf template class. This also helps to offer the whole project under PUBLIC DOMAIN now.
