All changes that you make in Google Chrome, for example your home page, what toolbars you use, any saved passwords, and your bookmarks, are all stored in a special folder, which is called a user data directory.
chrome.exe "--user-data-dir=C:/Users/MyUser/AppData/Local/Google/Chrome/User Data"To set the profile directory for our sample web application, you can use the following code:
const sCmdLine = """C:\Program Files (x86)\Google\Chrome\Application\chrome.exe"" --user-data-dir=D:/temp/SilkTest --profile-directory=Profile1"
