How to Create a New Folder in Mac OS X Lion
Think of creating new folders in Mac OS X Lion the same way you’d think of labeling a new folder at work for a specific project. New folders help you keep your files organized, enabling you to reorganize them just the way you want. Creating folders in Mac OS X Lion is very simple.
Decide which window you want the new folder to appear in, and then make sure that window is active.
If you want to create a new folder right on the Desktop, make sure that no other window is active.
You can make a window active by clicking it, and you can make the Desktop active if you have windows on-screen by clicking the Desktop itself.
Choose File→New Folder (or press Shift+Command+N).
A new, untitled folder appears in the active window with its name box already highlighted, ready for you to type a new name for it.
Type a name for your folder.
If you accidentally click anywhere before you type a name for the folder, the name box is no longer highlighted. To highlight it again, select the icon (single-click it) and then press Return (or Enter) once. Now you can type its new name.
For folders and files that you might share with users of non-Macintosh computers, here’s the rule for maximum compatibility: Use no punctuation and no Option-key characters in the folder name.
