Rules for folder names

When you choose a name for your folder, remember the following:

• The name can contain only the following characters: uppercase letters (A-Z), lowercase letters (a-z), numbers (0-9), periods (.), hyphens (-), tildes (~), underscores (_), equal signs (=), and colons (:).

• The name must be at least one character long. Empty folder names (such as folder1//folder3/) are not allowed.

• Names are case sensitive. For example, you can have a folder named myFolder and a folder named myfolder in the same container or folder because those names are unique.

• The name must be unique only within its parent container or folder. For example, you can create a folder named myfolder in two different containers: movies/myfolder and sports/myfolder.

• The name can have the same name as its parent container.

• The folder can’t be renamed after it has been created.
