Some time its not possible for me to delete anything from my computer which is used by system already. Like if you click to delete it, its give you a message that Could not delete (Program is running / or already to use) So is there any way to fixing this problem ? I want to clean some of my junk files in computer.

Yes this is possible with a tool. I know the way to delete any data from computer if its being used by other sources. Like i remember when i was try to clean my uninstall software folder. Its give me error that this program is already use. So I just go in google and type the title "delete used program" and find this software for me. You must try

Unlocker

Thanks for sharing this great tool. Yes I need also because of having same problem. Anyway Would you please explain more about how to use it ? Because I installed it. But could not understand because I could not find in my startup. What can i do ?

I also use this tool after reading post from this forum. Anyway Its very easy. If your program is busy and not deletable just right click on that program. Then you can see a option "Unlocker" Click and chose a option you like. Its delete after rebooting,kill the process and delete,rename. Its very easy.
