Windows 7: :BDU:$DATA (alert) ... when copying EXE files

:BDU:$DATA (alert) ... when copying EXE files

When I copy paste EXE files from one drive/folder to another I sometimes get a windows-alert .....

Q1: What does this all mean ?
Q2: Am I doing something wrong ?

Looks like an Alternative Data Stream.

Probably some third-party application or something.
