The File Browser Option
The File Browser gives you the ability to inspect and manipulate files and directories. The File Browser is shown in Figure 31.12.


Figure 31.12.  The File Browser.
It consists of four subviews that are described in Table 31.7.

Table 31.7. The File Browser subviews.



Subview
Purpose



path-label field
Shows the name of the current directory.

file pattern field
Allows a search pattern to be entered for choosing files for the file list.

file list
Shows a list of file and directory names.

contents view
Shows the contents of a selected file.



To inspect the contents of a file, double-click the left mouse button on the name of the file in the file list. To change directories, double-click on the directory name. Directory names are always shown in the file list.

You can use the file pattern field to display the list of files matching the specified pattern. The default is *, which shows all files. The search pattern can be changed by moving the pointer to the field, editing the pattern, and then pressing enter or choosing accept from the file pattern pop-up menu.
As in the other browsers we have discussed, each subview has a pop-up menu that is activated by the menu mouse button. The path-label pop-up menu is shown in Figure 31.13.
