While working, many computer programs and also Windows itself create a lot of temporary files. These files are not harmful in themselves, but they tend to accumulate and take up a lot of disk space. Also, when your disk space is low, Windows will work slower than usual.
The Windows Temporary Files wizard searches for the temporary files, and then allows you to select which temporary files you wish to delete.
The screenshot above presents the second step of the wizard. You can use the buttons to select or examine the files found. When you press the Next button, the selected files will be deleted and a report will appear.
Please note that this wizard avoids deleting the files that are in use when you run it, so it doesn't disrupt other applications.
You can also safely delete all your Windows Temporary Files in one go by using the Quick Cleaner.
