+In this example, the user `marie` has three inactive, i.e., expired, workspaces namely
+`my-workspace` in `scratch`, as well as `foo` and `bar` in `ssd` filesystem. The command `ws_restore
+-l` lists the name of the workspace and the expiration date. As you can see, the expiration date is
+added to the workspace name as Unix timestamp.

+!!! hint "Deleting data in in an expired workspace"
+
+    If you are short on quota, you might want to delete data in expired workspaces since it counts
+    to your quota. Expired workspaces are moved to a hidden directory named `.removed`. The access
+    rights remain unchanged. I.e., you can delete the data inside the workspace directory but you
+    must not delete the workspace directory itself!
+
+#### Expirer Process
+
+The clean up process of expired workspaces is automatically handled by a so-called expirer process.
+It performs the following steps once per day and filesystem:
+
+- Check for remaining life time of all workspaces.
+  - If the workspaces expired, move it to a hidden directory so that it becomes inactive.
+- Send reminder Emails to users if the reminder functionality was configured for their particular
+  workspaces.
+- Scan through all workspaces in grace period.
+  - If a workspace exceeded the grace period, the workspace and its data are deleted.
