Many of us started here:
All you had to do was ask...but there's one thing that has been plaguing me.
In windows, I can highlight a bunch of folders and right-click->properties and it will give me the TOTAL amount of files and space in one window. I have yet been able to figure out how to do it in OSX without having to make a parent folder, move all the folders into that folder, and then "get info" on the parent. Not ideal.
(What happens on the OSX side, is that if I get info for multiple folders, it pops up an 'info screen' for each folder selected...)
Not sure if that info will be useful for the OP, but I know a few people that have that same issue. Seems like it's a basic function not to be able to do?
