    <p>I answered this in a <a href="https://stackoverflow.com/questions/1447575/symlinks-on-windows/7924557#7924557">similar question</a>, so I'll copy my answer to that below. Since writing that answer, I ended up writing a python-only (if you can call a module that uses ctypes python-only) module to creating, reading, and checking junctions which can be found in <a href="https://github.com/Juntalis/ntfslink-python/tree/master/ntfslink" rel="nofollow noreferrer">this folder</a>. Hope that helps.</p> <p>Also, unlike the answer that utilizes uses the <strong>CreateSymbolicLinkA</strong> API, the linked implementation should work on any Windows version that supports junctions. CreateSymbolicLinkA is only supported in Vista+.</p> <p><strong>Answer:</strong></p> <p><a href="https://github.com/juntalis/ntfslink-python" rel="nofollow noreferrer">python ntfslink extension</a></p> <p>Or if you want to use pywin32, you can use the previously stated method, and to read, use:</p> <pre><code>from win32file import * from winioctlcon import FSCTL_GET_REPARSE_POINT __all__ = ['islink', 'readlink'] # Win32file doesn't seem to have this attribute.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
