where did comodo dragon save history?

i want to know where did comodo dragon save its history
it is because i want to include comodo dragon browsing history into CCleaner software from piriform.com so i dont need to clear browsing history from the browser again
or if you could help,just tell me how to do it plz
thanks for the great software anyway

It is saved along with everything else like bookmarks, extensions etc. in;

c:\Documents and Settings<User Name>\Local Settings\Application Data\Comodo\Dragon\User Data\Default\

If you want to back up your profile in case of a reinstall or for installing on another computer etc. this is also the directory you would want to back up on occasion. You can either do it manually or using a backup utility.
