The Application layout » File view branch of Settings has the following options.
If selected, volume labels rather than just drive letters will be displayed under the Explorer tab in the file view.
If the Show volume labels in Explorer view option above is selected, the format defined in this field will determine how the volume label is displayed under the Explorer tab in the file view.
If selected, system registered icons will be used under the Explorer tab in the file view rather than generic file type icons.
If selected, the editor will detect empty folders in the Explorer view in the file view. Those folders determined to be empty will NOT have a "+" shown beside them (indicating that they may be expanded). If this option is not selected, the "+" may or may not be accurate, but will not be updated until you attempt to update / expand a folder.
When the cursor hovers over a drive in the Explorer view, the editor attempts to get the latest information about that drive and display it. If this option is selected, drive information is cached and the drive is not accessed so often.
If selected, a single click in the Open file list in the file view will activate that file in the editor. By default this option is not selected and only a double click will activate the file.
If selected, linked files will be opened when the lnk file is clicked on in the Explorer view, and the Explorer view will navigate to the linked directory when the lnk directory is clicked on in Explorer.
If selected, a "Network" node is displayed in the Explorer pane of the file view. When this node is expanded, a listing of the members of the network to which the system is currently connected is displayed. You can then navigate this tree and access remote servers without mapping drives. Paths for files opened via this method will be accessed and referenced using Universal Naming Convention (UNC) format.
