During our every day use of Windows, it is common to meet a scenario read as the picture below. This message box appears when we are deleting something used by another process. But it is quite a pain to find out which process it is. In this case, usually we have to unlock the file with the help of tools, Unlocker, for example, so that we can remove the file easily.
However, now in Windows 7, we don't have to do so. The system itself has a built-in feature named Resouce Monitor which can help us to find out which process is using the file. For example, if we need to delete sting--_shape of my heart.mp3 on my desktop, generally we will see this when we try to remove it.
Now, let's find out which app is playing or using it.
* Just right-click on the taskbar and open Task Manager
* Turn to Performance tab and hit Resouce Monitor
* Switch to CPU tab, and here you will see Assiated Handles
* Type in sting--_shape of my heart.mp3 in the box
* See what?just right-click on the process to end it
* Now remove the file.
