Difference between nt:folder, sling:folder & sling:orderedfolder in AEM?

Question

I want to know what if is difference between nt:folder, sling:folder & sling:orderedfolder in AEM/CQ?

Also what are cases to use each of these while implementation?

Answer 1

• nt:folder can be used as a "vanilla" folder node in the JCR

• Using a sling:folder allows the folders children to be interpreted using their sling:resourceType — e.g. if you had a node "bar" at /etc/designs/foo/bar, setting the resource type of "foo" to a sling:Folder allows you to resolve bar using its resource type via a script (just like with components), whereas if "foo" were an nt:folder this wouldn't be possible (it would just be treated statically).

• sling:OrderedFolder can be used when ordering is important, e.g. in the /etc/map directory, if you want your entries to be used in order rather than randomly, the ordered folder provides this option. (For most cases, it's not really needed.)
