When saving a message to a different folder collection, you can
    select PREV COLLECTION or NEXT COLLECTION to get to the folder
    collection you want to save to. Here, "Prev" is an abbreviation
    for "Previous". By default, the first folder collection is the
    one to save to.

    For local or remote OpenVMS servers, you can also specify the
    file name where the folder resides directly as

    #disk:[directory]mailfilename#foldername

    when prompted with the folder name. If you are saving to the same
    file in the folder collection, then only the folder name itself
    is needed.
