Internal field "tc.file type" returns "file" for file symbolic links.
Expected "reparse point" value.
Symbolic links may be detected by IO_REPARSE_TAG_SYMLINK reparse point tag. If object has attribute flag FILE_ATTRIBUTE_DIRECTORY set, it is a directory symlink, else it is a file symlink. File symlinks have flag FILE_ATTRIBUTE_REPARSE_POINT set as any other reparse points.
TC detects directory symlinks normally, but file symlinks detected as just files.
To create symlink you may use Windows Vista/7 internal command mklink. For example,
mklink D:\LinkToReadme.txt D:\Docs\Readme.txt
