There are many ways to clean a file, but the most common is to use the Windows cleaning utility, “Cclean.” Cclean can be found in the Start menu and is usually named “Cclean.” To start Cclean, open it and click on the “Clean” button. This will start Cclean and ask you to choose a file to clean. If you don’t have any files to clean, Cclean will default to cleaning all of your current files. Once you’ve chosen a file to clean, click on the “Clean” button. This will start Cclean and ask you how much time you want it to take. You can also choose whether or not to delete any files that were left behind by Cclean. If you’re happy with how Cclean is working, click on the “Finish” button. If you’re not happy with it, you can always change some of the settings if desired.
