Your user profile in Google Chrome stores data about your browsing activity, including your history, bookmarks and cookies. Chrome does not include a method to export your profile from within the program, but you can manually copy the profile data in order to keep a backup, move your customizations to a new computer or set up a standardized profile for multiple computers in your office.
Exporting Your Profile Data
Before exporting, you may want to clear your cache in Chrome to reduce the size of the profile. Close all Chrome windows before continuing. Press "Windows-R," type or paste "%LOCALAPPDATA%\Google\Chrome\User Data\" (without quotes) into the Run window and press "Enter." Using the right mouse button, drag the "Default" folder onto your desktop, a USB drive or wherever else you want to save the profile and pick "Copy Here."
Importing the Profile
To use your exported profile, close any Chrome windows and move your "Default" folder copy into %LOCALAPPDATA%\Google\Chrome\User Data\ on any computer with Chrome installed. This will overwrite the existing profile unless you move or rename the existing "Default" folder first. If you're moving to a new computer, you need to install Chrome before restoring the folder.
