Double clicking on a wallet in the KWallet Manager window will open a new window displaying that wallet's contents. A wallet may contain any number of folders, which allow storing of password information. By default a wallet will contain folders named Form Data and Passwords.
The window has three sections:

A search line to filter the items of the current wallet
The tree view of the folders contained in the wallet. Click the > / v symbols to expand or collapse the tree view.
The contents of the selected folder entry at the right side. By default the password and value are hidden. To display and edit them enable Show values or click the Show Contents button.
Folders may be added, deleted or renamed via the context menu, and selecting a folder will update the folder entry list and the summary display. Selecting a folder entry will update the entry contents pane, and allow you to edit that entry.

Entries may also be created or deleted via the context menu for the folder contents.
All folders and entries may be dragged and dropped into other wallets or folders respectively. This allows a user to easily package up a new wallet for transfer to another environment. For instance, a new wallet could be created and copied onto a removable flash memory device. Important passwords could be transferred there, so you have them available in other locations.
Open the context menu with the mouse button click on Maps or Passwords in the Folder tree view. Select and choose a name for the new entry.
In the folder contents pane select New Entry from the context menu. For passwords click the Show Contents button, enter the new password. For Maps you have to add a Key and a Value. Click the Save button to store the new entries in the encrypted wallet file.
