Usually, these unnecessary, or junk files appear as a result of program's incomplete uninstalls, Temporary Internet Files, or elsewhere.

It is best if these files are wiped out from time to time, since they may, at some point, use a considerable amount of space on your drives.

Wise Disk Cleaner, with its intuitive and easy to use interface, helps you quickly wipe out all the junk files. There are two ways in which you can do that. If you are a beginner, you may use the wizard and use the program's default settings in order to clean-up your system.

In you are an advanced user, you can customize the operations: you can manually select folders to be cleaned-up, you can erase files with certain extensions, or exclude folders from the scan.
