There is a tree view on the main screen. Selecting an item in the tree allows you to view the contents of a specific feature.
If you select a item in the tree you can view and edit it's data.
For wallpaper and ringtones you can right click on items to get a menu or you can just drag and drop new files into BitPim.
For phonebook and calendar, you double click on the item you want to edit.
More detailed help is available in the Tree Items reference.
BitPim automatically saves all changes to your hard disk. There is no need to manually save or load information from disk.
When you are happy with changes you have made you can send them to the phone.
