On this website, pages in any one namespace can be arranged into a hierarchy of folders that is approximately analogous to the directory structure of computer operating systems. On QED, the folder-delimiter character is "/" in all namespaces except for the Image: namespace.
Anyone who is logged in can create a new folder, but if you want to create a new top-level folder, please first review the guidelines for creating a new folder.
The folder delimiter character is "/" except in the Image: namespace, in which it is "=".
A top-level folder is one whose name contains no interior folder delimiter character. Thus MG/ is a top-level folder.
The root page of a folder is the page whose name is the folder's prefix up to but excluding the first folder-delimiter character. Thus the root page of the MG/ folder is the page: MG.
Links to pages within a folder are most easily created and maintained using relative hyperlinks, e.g. rather than typing [[Tibetan Buddhism/Glossary]] on the [[Tibetan Buddhism]] page, one can simply type [[/Glossary]]. See Relative Hyperlinks for help.
A distinguishing logo and customized left-hand side navigation menu can be assigned to each top-level folder. This affects the appearance of the root page and all its subpages, as can be seen by visiting the MG page.
For details about these and other per-folder customizations, see Help:Customization.
Folder-Based Access Control
Restricting read-access and/or write-access to pages and files on this website is often accomplished by defining access control lists that affect all pages within a top-level folder.
The main mechanism for defining folder-based restrictions is documented at Folder-Based Access Restrictions.
Additional restrictions can be defined on a page-by-page basis within a folder using Category-Based Access Restrictions.
