Subject: [EXTERNAL] SET_REPARSE_POINT vs QUERY_DIRECTORY?
Hello dochelp!
Attached find a network trace against Windows 2016 server that creates a symlink and tries to query it via QUERY_DIRECTORY.
In frame 19 a symlink x->y is successfully created.
When listing the directory, frame 24 just shows FILE_ATTRIBUTE_ARCHIVE for "x". Only if "x" is closed in frame 29, the listing shows FILE_ATTRIBUTE_ARCHIVE | FILE_ATTRIBUTE_REPARSE_POINT in frame 34 as expected.
Question: Is this relevant, and where is this documented?
Thanks, Volker
