A 'folder' in Microsoft Windows is the same as a directory, and directories are indicated by the folder icon. When the Librarian Interface creates a folder it is actually creating a directory. However, we continue to use the more familiar term 'folder'. Folders are used in the tree to group files together, and to introduce structure that makes it easier to find files. Folders can be placed inside folders. There is virtually no limit to how many folders you can have or how deeply they can be nested.

To create a folder, select a non-read-only folder from either tree and click the New Folder button. A folder called 'New Folder' appears within the selected one. [Renaming files using Java is problematic, so for the time being it is disabled. If you rename this folder using some other method, the new name will be visible the next time the tree is refreshed; when it parent folder is collapsed and expanded, or when the collection is reloaded].

Folders can be created more conveniently using the right-click menu. Move the mouse pointer over the parent folder and click the right mouse button. A menu, just like those in the menu bar, appears below the mouse pointer. It may have just one item, or several of them, depending on what item you clicked it over. Choose the New Folder item to create a new child folder exactly as above.

You can create several folders, one after another, without having to rename them in between. They will be given names New Folder 001, New Folder 002, and so on.

If a folder is read-only, the Librarian Interface cannot change its contents. You are probably trying to create a folder where you're not able to.
