From Rosanne Cashriel:
Folders-Full Set is a project to provide you with endless numbers of folder icons to replace all the default blue Apple folder icons on your Mac. Icons are provided for the HD, applications folders, home and for every layer of folders on the Mac starting from the first HD subdirectory and from the first home subdirectory - both of which I called "Layer 1" - to the last layer of folders under each of these directories which is "Layer 11". Each layer of folders supplied here has an allocated colour for the folders' tabs with matching "jewel" apples on the folders' fronts complementing their unique icons. Instructions for replacing icons are included in the read me file together with other useful tips. Obviously, this set of icons can never be complete especially as regards to application folders, however, you can contact me with your requests for further folder icons which I will add to my request list and create the icons to be added in subsequent versions the releases of which are wholly conditional on user donations.
