FILE_ATTRIBUTE_DIRECTORY

NTFSD

If I issue IRP_MJ_DIRECTORY_CONTROL/FileBothDirectoryInformation and after
its completion FILE_BOTH_DIR_INFORMATION->FileAttributes contains
FILE_ATTRIBUTE_DIRECTORY flags can I be sure that file is a directory?

FILE_STANDARD_INFORMATION.Directory may be more reliable.

I seem to recall, perhaps incorrectly, that FILE_ATTRIBUTE_DIRECTORY may get overloaded to mean more than just directory.

What about Rob Fuller’s statement?

“I seem to recall, perhaps incorrectly, that FILE_ATTRIBUTE_DIRECTORY may
get overloaded to mean more than just directory.”

In all fairness, I may just be paranoid from having worked around a lot of bugs on this platform over a lot of years. The question is am I paranoid enough?

Rob is talking about the options where both FILE_DIRECTORY_FILE and
FILE_NONDIRECTORY_FILE are set. These are not ATTRIBUTES, but options set
on create.
