Wise Duplicate Finder can free up drive space by finding and deleting duplicate files by name, file size or contents.Once installed you are presented with two options. First, you select a folder or folders. You can choose your entire drive; however, we've never been a fan of doing this as Windows does have duplicate files that you don't want to delete. Next, you select how you want to find duplicate files: Match Name and Size (Fastest) Partial Match (Fast) Exact Match (Slow) 0 Byte filesThese four options narrow down exactly how you will find a duplicate file. 0-byte files can be useful just to get rid of garbage, primarily.You can add as many folders as you like and remove folders from scanning with the X next to any folders already selected.Support is offered by online help, their forums, the main website and a contact link. You can check for updates, modify default settings and even restore a file in the menu.Wise Duplicate Finder is free, fast and efficient. There is a pro version available in the $15.00 range, but we can't find what the limitations are. Typically this includes support and automatic updates, for example, but if you find Wise Duplicate Finder useful, it's hard not to kick in fifteen bucks just to say thanks.
