i posted here before with the saim problem, i have an important test on friday and i have many web pages i visited in the pat week that i need to learn, i mistakably deleted my explorer history, and from the last time i took a lesson to backup history so i have the copy of the history folder (from 'C:\Documents and Settings\Jake Cohen\Local Settings' (folder originally hidden as system folder)), and i try to delete it (the exist one - without the necessary files that i expore before), in order to paste the one i copy yesterday. it gives me an error that it system folder and cannot be deleted, try to renamed it - nada, try to uncheck the 'read only' property - nothing. Please somone to help me with that.

thanks.
