You can group related spreadsheets into folders so they’re easy to find.
Click the desktop to make the Finder active, then choose File > New Finder Window (from the File menu at the top of your screen).
In the Finder window, navigate to where you want to create the folder (for example, the desktop, the Documents folder, or a folder on iCloud Drive).
If you create a folder inside the Numbers folder in iCloud Drive, the folder appears in the spreadsheet manager on your iOS devices only when it contains a spreadsheet.
Choose File > New Folder.
If the New Folder command is dimmed, you can’t create a folder in the location you chose. For example, you can’t create a folder in the All My Files section of the Finder sidebar.
Enter a name for the folder, then press Return.
To move a spreadsheet to the folder, drag it there.
You can also create a folder when you save a new spreadsheet in Numbers.
Important: You shouldn’t rename app folders (such as those in the Applications folder), folders that came with your system (such as the Library folder), or your home folder—the one with your name on it.
Click the folder, then press Return.
Enter a new name, then press Return.
You can use numbers and most symbols. You can’t include a colon (:) or start the name with a period (.). Some apps may not allow you to use a slash (/) in a filename.
To save any of the spreadsheets in the folder before deleting it, move them to other folders or the desktop.
Select the folder, then do one of the following:
Hold down the Command key then press Delete on the keyboard.
Drag the folder to the Trash icon in the Dock.
The folder and its content aren’t permanently removed from your computer until you empty the Trash (click the desktop, then choose Finder > Empty Trash from the Finder menu at the top of your screen).
