Open file path

Any method or script wherein i type in the command line and then run blender and try to open a file and open window should open in the path that i have typed in the command line.

The reason is that i have many blender works files on a cd within a directory where the blender work file and scripts and image regarding that file are present. so all i want to do is create a batch file and the execute it at command line and then run blender and when try to open a work file its dialog box should be in that path.

Thanking you.
