 ===G. Workspace===
 
-We'd like to propose to set up workspace if your EDC collections are consisted of multiple edc files. The function of Enventor workspace is disabled in default but if you launch Enventor with "-w" command option which specifies a workspace path, then Enventor regards that folder path is workspace directory. Once the workspace is specified, traditional File browser (toggle hotkey, F9) and File tab (toggle hotkey, F11) are available in Enventor so that you could navigate multiple edc files in that tools.
+Set up workspace if your EDC collections are consisted of multiple EDC files. The default workspace directory is where you launch the Enventor but if you launch Enventor with "-w" command option which specifies a workspace path, then Enventor regards that path is a current workspace directory. Workspace is designed to be used with the File browser (toggle hotkey, F9) and the File tab (toggle hotkey, F11) so that you can navigate multiple EDC files in those tools. Basically, the file browser displays the current workspace directory.
+
+
+==File Browser==
+
+You can open EDC files in the file browser. Just double click any EDC files on it. Then EDC text will be opened with a new file tab.
+
+Enventor allows only one main EDC file that can be activated in the Live view. In the file browser, the main EDC file will be displayed with [main] tag. If the main EDC file contains multiple sub EDC files, then you can open and navigate through them. You can easily open those files in the file browser but you can also open them by pressing "F3" if the text editor cursor is placed on the "include" line in the text view. (ie, #include "subfile.edc").
+"F4" shortcut key helps you to go back to the previous edit page quickly.
+
+Enventor tracks a current focused EDC group to display it while you go through groups in one EDC collection. But If you open an new EDC file which contains an another collection, then you need to manually set up that file to be a main. For this, press "F2" after select a new main EDC file in the file browser. Then Enventor understands that EDC has a collection to be activatable with its subordinates files. You can also change a main EDC file in "Settings -> EDC Build -> Main EDC File".
