 In order for PMA.core to show content, you need to set up root directories. A root directory is a starting location from which your various whole slide images will be hosted.

+Working with root directories offers several advantages:
   * You don't have to navigate through a complicated directory structure before reaching the files that you want to work with
   * You can map multiple root directories to organize slides according to different purposes or workflows.
-  * Swtich out different types of storage without the end-user knowing about it. When you move data from a conventional hard disk to cloud, you typically need to install a new piece of software (S3 browser, or an FTP explorer). With PMA.core, you just re-direct the root-directory to point to the updated location and you're done; the end-user remains unaffected

 The mounting point of a root directory refers to the base directories where the system should look into for whole slide images. All the subdirectories of the root directories are exposed by the application and whole slide images that are discovered are advertised.

 ==== Configuration ====
-We have a [[rootdir_config|separate section]] in this wiki that takes you through the different steps that you can take to [[rootdir_config|configure root directories and mounting points]].
+**Root directories management**
-We also talk about the security precautions that you can take when configuring these.
+Root directories can be managed by selecting the "Root directories" option under the "Settings" section in the left menu.
+{{ :roots.png?nolink&400 |}}
+The list displays all the configured root directories and provides options to add new, edit and delete entries.
+  * The "Offline" column indicates whether or not a root directory is enabled. An offline root directory is not advertised by the system and its contents are not available to end-users.
+  * The "Path exists" column indicates whether or not the system is able to mount a root directory's path and access it's contents. For example, a root directory that points to a delected local file system folder will not have the "Path exists" column checked.
+We have a [[rootdir_config|separate section]] in this wiki that walks you through the different steps of [[rootdir_config|configuring root directories and mounting points]].

+=== Edit ====
+You can edit the following properties of a root directory
+^ Parameter                ^ Meaning  ^
+| Alias | The unique name or alias for the root directory |
+| Description | An aribitrary string that can help an administrator remember what your root directory contains. The Description field of a root directory can also be used to hide additional information about a group of data that you don't want everybody to know about immediately. Do //not// use this field for sensitive information, as it can be seen by everyone with access to PMA.core. If you're an instructor working with students, it's perfectly ok to enter reminders for yourself in this field like "these are all trick-questions"... |
+| Quota   | You can set a limit on the amount of data that you want to allow PMA.core to manage in a particular period. This can be useful when facilitating temporary workers, visiting staff, residents or other students that will only be at your department for a brief period of time. If you //don't// want to restrict the amount of data, you can leave the default value of 0 in place. |
+| Offline | When checked, the folder will not be available to downstream applications like PMA.studio. Maybe you're just creating a placeholder for a future department, or you're not done curating a new collection yet. Instructors can also use this option to prepare a list of exam slides and only expose them to students for a limited amount of time (we don't offer scheduling at this moment though; you're still going to have to flick the proverbial switch manually) |
+| Prevent rendering of labels/barcodes | This prevents the labels or barcodes of any slides in this root directory from being shown. This is primarily used to anonymize the slide |
