<div>purge: delete invalid junction point</div>
<div><br>
</div>
<div>When you have 2 folders linked to each other by a junction point. For exemple</div>
<div>"A" is a folder and "B" is a junction point to "A". "A" is deleted, then</div>
<div>os.listdir throws an error on "B" because the target of "B" doesn't exist</div>
<div>anymore.</div>
