Was getting pissed off when opening a CAB file in Windows 7, coping all files then trying to paste them in explorer.  Constantly kept asking the “File Download – Security Warning”.  I wasn’t going to sit through 1829 files and click SAVE, SAVE, SAVE, SAVE.   Couldn’t get rid of the fing message.

So found Expand, built into CMD.

Go to the directory the CAB file is in.


expand E6420.cab -f:*.* c:\drivers
