Pressing <keycap>SPACE</keycap> a second time will toggle the marking of the directory without affecting the selection status of other files/directories.</para></listitem> <listitem> <para>To calculate how much disk space is occupied by the marked files and directories in the active panel select <emphasis role="bold"><menuchoice><guimenu>File</guimenu> <guimenuitem>Calculate Occupied Space</guimenuitem></menuchoice></emphasis>. After a (hopefully) small delay, a dialog box will be displayed with total occupied space and the number of files and directories you selected. The space occupied by every selected directory will be shown as if the user just pressed <keycap>SPACE</keycap> on that directories. If the active panel is browsing an archive, the numbers will apply to the *unpacked* size of the selected files and directories, not their compressed size. After the calculation the marking state will toggle and the cusor will move one position down.</para> </listitem> </itemizedlist> Calculating the occupied space on remote filesystems is supported. <note><para>Performing this operation on a very large filesystem (thousands of files) may be time consuming.
