... I just use terminal though:
Code:chflags -R nouchg ~/pathwithstufftounlock
Why is an action needed? Why not just select them all, do a cmd+option+i and unlock them all from there.
If everything is in separate folders switch to List view, do a cmd+a to select all the folders, tap your right arrow key so all the folders open, do another cmd+a to select them all (repeating previous steps obv for any sub folders) and do the unlock.
Nice...
