You can now select any number of files from the Mac OS X desktop or a folder and create a new folder containing those selected items:
- Select files you want to create a new folder containing
- Right-click on one of the selected files and choose “New Folder with Selection (x items)”
You can also select the items and go from the “File” menu in the Finder to the same “New Folder with Selection” option, but right-clicking is quicker. There’s supposed to be a keyboard shortcut to do this too, Control+Command+N, but it doesn’t seem to work on any of the Macs I’ve tested, give it a try and maybe it will work for you.
