Basic tasks such as moving and copying files is generally so straightforward we don't even give it further thought. simply select the required files and copy or drag to your desired location. However, sometimes simple problems such as a file being in use can interfere with the copying process. This could cause a file not to be copied correctly, and can cause confusion when copying multiple files. Instead of using the Windows Explorer it may be worth using an application that offers notification of any problems during copying. 21 Jan 2010
