Wise Disk Cleaner 4 Pro helps us to dispose of all useless files from the computer. It contains predefined database of extensions and their mostly used locations. Naturally, we can add own settings.  After the scan is finished the program displays the list of files and allows us to see what exactly we are going to remove. Maybe you will prefer to make a backup first before you start the scan, and move the backup files into the assigned directory, and make sure you will not lose any of your important data.
We can use the defragmentation tool since it is included in this program. Program supports hard drives only (does not support USB flash drives or memory cards).
