Zitat von
winhelponline:
The lock (padlock) overlay icon appears for files/folders which are private, but located under a non-private directory. Per Raymond Chen [MS]:
A private item is an item where the only user account with
access is you.¹ You create one of these, for example, by going to the sharing wizard and saying Share with: Nobody. To avoid clutter, the overlay is shown only when there is a transition from non-private to private. (Otherwise you’d have a lock overlay on everything in your Documents folder, for example.)
¹Even though you are the only user account, there can still be
access granted to groups and non-user accounts such as the Administrators group and the SYSTEM account.
(Wobei in den Kommentaren gemeckert wird, das Chen nicht ganz korrekt beschreibt...)
