Creating New Folders
If you aren't already running Konqueror, start it up now and make sure you are in your personal home directory. In the main Konqueror window, right-click on any blank area and look at the menu that pops up. Move your mouse pointer over the top item (Create New), and you'll see a secondary menu appear. The first item is Folder, as in "Create new folder." Click here, and the system will prompt you for a folder name. This can be pretty much anything you like. If this folder will house your music files, perhaps its name should be Music.
Just remember that you can create folders inside folders, and you can start organizing things in a way that makes sense. For instance, you might want to create folders called Rock, Jazz, Hip Hop, and Classical in your Music folder.
"I've Changed My Mind," or Renaming Files
You created a folder called Classical, and you really meant Opera. You could delete the folder or you could simply rename it. To rename a file or directory, select it, right-click to get the menu, and then choose Rename. The name will be highlighted under the appropriate icon—just type the new name and press <Enter>. Alternatively, select it and choose Rename from the Edit menu in the menu bar. The easiest way of all is to press <F2> after you have selected the file or directory.
