You can configure (or roll back) an individual folder or item to a specific view label, promotion state, or date and time. Essentially, all rollbacks are made to a particular date and time. For example, if you roll back to a view label, you essentially roll back to the revision of the folder or item that existed on the date and time at which that label was attached. Unlike a view, a folder or item retains its roll-back configuration until you manually change it or until the folder or item branches. When you close the view, the folder or item does not immediately return to its current configuration.
Rolling back a folder does not re-configure any of the items or child folders associated with it. It only rolls back the folder properties to the values they had at the configuration time. Depending on the folder behavior, the folder may become read-only, in which case its properties cannot be changed.
The configuration of a folder affects the new items or child folders that can float into it. For example, in a floating branch view, you can keep items from floating into a particular folder by configuring the folder to a particular label, promotion state, or point in the past. Later, you can re-configure the folder to floating so that it can receive new items from its parent. However, the items added to the parent while the folder was not floating will never automatically go into the folder. They must be manually shared. To freeze a folder or item at a certain point in time so that it cannot be changed:
