Messages can quickly accumulate in your INBOX folder. If you use email often, you soon could have hundreds. You need to delete messages you do not want, and you can use folders to organize messages you wish to save. A folder is a collection of one or more messages that are stored (just like the messages in your INBOX) so you can access and manage them.
A full list of the folder management facilities supplied by Pine is given in ``Folder index screen and commands''.
