Use the file reverse selection function of Windows 7 system

A lot of times, we need to use the inverse selection function when deleting files, so as to avoid the trouble of manual selection by item, but you may not find this function from the right-click menu under Windows 7. In fact, Windows 7 is of course providing file deselection, but it is hidden. You can enable this function by the following steps:

Step1: Select a file to be retained, press the Alt key, and you can find the reverse selection command from the Edit menu. After you select it, you can complete the reverse selection task.

Step2: If you feel that it is more troublesome to press the Alt key each time, you can open the Folder Options/View dialog box and check the Always show menu check box in the Advanced Settings list box. Using the edit menu should be a lot easier.
