In the Git Winch Client Application the left hand side shows the entire list of folders of your computer. And when you start the application, initially it will directly take you to the Work Folder that you had set in the .ini fie of this application. However you would be able to see ALL the folders and files of your computer.
Important note
The left hand side of the application ONLY shows the folder tree. To see the files in a particular folder, select that folder and the files inside that particular folder will be shown on the right hand side.
By default, Git Winch is ONLY going to handle work happening inside the data folder and in the sub-folders inside that.
Pop-up Menu
When you right click in this area, you can get a list of commands that you can activate. Those commands only work on the selected folder in the tree. Most of these commands would be for carrying out some Git actions.
