@burnout426, where can I find the "Web data" folder? Thought it is in this directory but there isn't such a folder:

C:\Users{Username}\AppData\Local\Google\Chrome\User Data{profile}

{profile} is by default "Default"

Same goes for the Opera folder - where can I find it?

Lastly, how can I keep BOTH browsers in sync as I update the search engines? Thank you.

I have hundreds of custom search engines in Chrome. Is it possible to export from Chrome & import into Opera or even Better - keep them in sync all the time as I use them interchangeably?
