Disk Navigator menus are updated automatically when directory contents change, except the first menu, that is updated through the Options dialog.
The contents of the "Recent" section are saved in the /.kde/share/config/kpanelrc configuration file. If you want to clear this section, you can clear the RecentFolders and RecentFiles entries in this file after logging out from KDE.
Documents and applications not accessed through the KPanel are not added to the "Recent" section. This limitation will disappear in future versions of Disk Navigator.
Due to efficiency reasons, most files are not displayed with the same icon you would see in a file manager window. With the current version, only .kdelnk files have the corresponding icon displayed. Other files are displayed with two different icons to distinguish between data files and executables.
Copying ˜/.kde and $KDEDIR: if you are using symbolic links to define filesystem entry points in the Shared/Personal sections, you must be careful when copying the KDE directory, since the cp command with the -r option follows symbolic links. Under Linux you can use the -d option to avoid this problem. However, you are recommended to change all symbolic links to corresponding KDE URL files. Symbolic links are stored under $KDEDIR/share/disknav (Shared) and ˜/.kde/share/disknav (Personal).
