program that compares one directory to another using C#

Question

Please Help Me How to do this, as soon as possible, its very urgent, Thanks in Advance.

Source : C:\Data

Destination : C:\Backup\Data

Write a program that compares one directory to another "including sub-directories if user requires" and keeps them identical by copying or deleting files

and creating or deleting directories in the destination directory.

-> If a file is different in size or date and time then it should be replaced.

-> If a file is does not exist in the destination folder it must be copied.

-> If a file exists in destination but not source it must be deleted from destination.

-> If a directory does not exist in the destination it must be created.

-> If a directory exists in destination but not in source it must be removed from destination.

-> The whole process must be logged in a text file for viewing later.

-> The viewing of logs must be viewed by an external text editor like notepad etc.

-> Keep the data the user has entered in an xml file for ease of reuse.

-> Show a progress bar of the replication process. Create and use classes where possible. Use c# as the language.
