I made my invisible files visible with the lovely Cocktail utility, and then pasted a nice icon to the .Vols folder and put it in the Dock.
This way and new media automatically appear in this folder, and I can remove all my hard drives from the Dock - freeing up valuable space.
For some probably logical reason, my primary HD is not in .Vols, so I put an alias of it in there.
Then I made my usually invisible files invisible again...
Is this all safe, or have I done something really dumb?
