I want anything pasted in desktop automatically copied to another folder in next drive.

I think its impossible. you can take a diffrent way like shortcut folder or send to folder. or other way.

Yes, Syncback will do it.. synchronize files in different drives or folders. There is no native XP function to do it automatically.
To get Syncback to synchronize files every few minutes or whatever time interval you wish, you must make the profile and then place that profile into a Group Profile, which permits short periodic sychronization, instead of daily etc. It works with filters which enable selection of a single file or group of, directories etc.

Isn't it possible by editing the registry??????????
