<para
>Selecting a folder in the <interface

<sect2 id="howto-library-playlist-folders">
<title
>Cartelle delle playlist</title>

<para
>Folders in the <guilabel
>Now Playing</guilabel
>, <guilabel
>Recent</guilabel
> and <guilabel
>Playlists</guilabel
> section are known as playlist folders. When you open a playlist folder, the <interface
>list view</interface
> lets you expand its subfolders inside the same view, so that you have access to the entire contents of the selected folder. When you open a folder in another section, the <interface
>list view</interface
> will show the contents of that folder only, including the subfolders, and to access the contents of a subfolder, you can execute or <quote
>drill down</quote
> to the subfolder to open it.</para>

<para
>The <interface
>multimedia library</interface
> allows you to create an unlimited number of subfolders in a playlist folder or in a folder in the <guilabel
>Collection</guilabel
> section, and the subfolders can be nested to an unlimited number of levels.</para>

</sect2>

<sect2 id="howto-library-ordering-sorting">
<title
>Ordering and sorting</title>

<para
>You can arrange the contents of playlist folders in any order, by dragging items with the &LMB; and dropping them in a new place, or by using the <guimenuitem
>Move Up</guimenuitem
> and <guimenuitem
>Move Down</guimenuitem
> commands from the <link linkend="menu-library"
><guimenu
>Library</guimenu
> menu</link
> or the <link linkend="popup-library"
>library popup menu</link
>.</para>

<para
>Folders in other sections do not have this ability, but they let you sort their contents by any column, by <mousebutton
>left</mousebutton
> clicking the column header. To sort items in the reverse order, click the column header again. If you click the column header in a playlist folder, the folder and any expanded subfolders are likewise sorted by that column, while collapsed folders retain the custom order of items if they had it.</para>

<para
>The sorting column and direction (ascending or descending) is shared by all folders in the library, except playlist folders where you put items in a custom order as described above. So if you sort files in a directory by their time length, and then go to a folder in the <guilabel
>Collection</guilabel
> section for example, its contents will also be sorted by their time length.</para>

<para
>Subfolders are always listed before other items in folders that are not playlist folders, while in playlist folders subfolders are listed after other items unless you change the order manually and arrange the contents differently. As a result, when you play a playlist, the contents of a playlist folder will be played before the contents of its subfolders, again unless you set a custom order of items in that playlist folder.</para>

<sect2 id="howto-library-editing">
<title
>Gestione multimedia</title>

<para
>If you have some multimedia files on your computer, you can put them into the <guilabel
>Collection</guilabel
> and on the <guilabel
>Playlists</guilabel
>, by dragging files or directories from the <guilabel
>Home Directory</guilabel
> or <guilabel
>Root Directory</guilabel
> section or from &konqueror; File Manager and dropping them into the folder of your choice. Or you can select the files and directories in the <interface
>multimedia library</interface
> and use the commands on the <guisubmenu
>Add to</guisubmenu
> submenus of the <link linkend="menu-library"
><guimenu
>Library</guimenu
> menu</link
> and the <link linkend="popup-library"
>library popup menu</link
>.</para>

<para
>Another way of adding multimedia to the library is by using the <menuchoice
><guisubmenu
>Add</guisubmenu
> <guimenuitem
>Files...</guimenuitem
></menuchoice
> command, which uses the standard &kde; file dialog, or the <menuchoice
><guisubmenu
>Add</guisubmenu
> <guimenuitem
>URL...</guimenuitem
></menuchoice
> command, which lets you paste in the path to a local file or directory or the <acronym
>URL</acronym
> of a remote file or stream. Both commands are on the <link linkend="menu-library"
><guimenu
>Library</guimenu
> menu</link
> and the <link linkend="popup-library"
>library popup menu</link
>. You can also drag a link from &konqueror; Web Browser and drop it into the library.</para>

<para
>There are four commands that put multimedia on the current playlist that is shown in the <guilabel
>Now Playing</guilabel
> section of the library and in the playlist drop down box on the <link linkend="parts-toolbar-playlist"
>playlist toolbar</link
>. Again, all of them are on the <link linkend="menu-library"
><guimenu
>Library</guimenu

>library popup menu</link
>.</para>

<listitem

>, <guilabel
>Add to collection</guilabel
>, <guilabel
>Add to playlists</guilabel
> and <guilabel
>Add to new playlist</guilabel
> commands are also available in &konqueror; File Manager. Select the files and directories you want to add to the <interface

>right</mousebutton
> click to open the popup menu and select an action from the menu or from the <guilabel
>Actions</guilabel

<para
>When you drag and drop items and folders within the same section, &kplayer; will move them to the new location. If you want to copy them instead, hold the &Ctrl; key while dragging and dropping. To move multimedia to another section instead of copying it, hold the &Shift; key while dragging and dropping. To remove items and folders from the library, select them and choose the <guimenuitem
>Remove</guimenuitem
> command from the <link linkend="menu-library"
><guimenu
>Library</guimenu
> menu</link
> or the <link linkend="popup-library"
>library popup menu</link
> or press the <keycap
>Delete</keycap

<sect2 id="howto-library-linked-folders">
<title
>Cartelle collegate</title>

<para
>Adding a directory to a collection or playlist folder in the <interface
>multimedia library</interface
> creates a subfolder that is linked to that directory, so that when you put new multimedia into the directory or any of its subdirectories, it will show up in the folder or the corresponding subfolder automatically, or if you remove some files from the directory, &kplayer; will remove them from the library as well. Similarly, when you put a collection folder on a playlist, the new playlist folder is linked to the collection folder, and when you play a playlist, the new folders in the <guilabel
>Now Playing</guilabel
> and <guilabel
>Recent</guilabel
> sections are linked to the playlist folder.</para>

<para
>For example, if you take a directory full of <acronym
>MP3</acronym
> files and add it to the <guilabel
>Collection</guilabel
> section of the <interface
>multimedia library</interface
>, then take the collection folder and put it on a playlist, then play the playlist, and then go back and put some more <acronym
>MP3</acronym
>s into the directory, &kplayer; will see them and automatically add them to the collection, the playlist and the current playlist, and play them along with the other <acronym
>MP3</acronym
>s.</para>

<para
>If you play a playlist and then change the order of items in a folder in that playlist, the order of items on the current playlist will also change. The new order will be reflected in the <guilabel
>Now Playing</guilabel
> section and in the playlist drop down box on the playlist toolbar.</para>

<para
>To open the origin folder of a linked folder, select the linked folder in the <interface
>multimedia library</interface
> and choose <menuchoice
><guisubmenu
>Go</guisubmenu
><guimenuitem
>To Origin</guimenuitem
></menuchoice
> from the <link linkend="menu-library"
><guimenu
>Library</guimenu
> menu</link
> or the <link linkend="popup-library"
>library popup menu</link
>.</para>

<para
>When you add more items or remove existing items to a linked folder, it will break the link, and the folder will no longer be updated when there are changes in the origin folder. The folder icon will change to reflect that. When you change the order of items in a folder in the <guilabel
>Now Playing</guilabel
> section that is linked to another folder in the <guilabel
>Playlists</guilabel
> section, the order of items in the two folders will be different, but the current playlist will still get updated items from the playlist folder.</para>

<para
>To copy the folder contents instead of creating a link, hold the &Ctrl; key while dragging and dropping the folder into the new location. However, the copy process may take a while if the folder contains a lot of multimedia, and of course the new folder will not be updated when the original one changes, so this is not recommended.</para>
