Win7 can't copy files How to solve

First, the file can't be copied

In the example, a Word document is opened by Office2003 and is actually edited. When I select a Word document for copying with normal operations, the system pops up a dialog box prompting that I cannot copy.

Second, IObit Unlocker copy file

Right click on the file or folder to be copied, select IObit Unlocker in the pop-up context menu, open the IObit Unlocker interface, click the small arrow of the drop-down menu Select the Unlock & Copy option and the pop-up dialog box will select the copy path point to confirm. Files or folders that cannot be copied are easily copied.
