Best Free Duplicate File Finder For Windows

Duplicate files may seem harmless to many computer users. If only users knew that these files causes more trouble than good. They eat up hard disk space and system resources, further slowing down your computer. Before you will even know, your large 1 TB or more hard disk space gets filled up. All of these unneeded files causes chaos and increases disorganization in your computer system.

Recently, I started facing this inevitable issue myself. My hard disks, (internal and external, which is more than 6 TB in total) got filled up with files. As happens to any user having tons of disk space, I never organized them properly. I just saved them where ever I found space. Be it on the internal hard disk or external drives. The same version of files mercilessly cloned are now scattered across the different hard disks. That’s when the thought of organizing files came in my mind. But before that I should remove all the duplicate files from all the different storage drives. I tried to find the best free duplicate file finder software for Windows PC to help me out. During this search to find the best, I came across a number of freeware duplicate file finders. I am saying “best” as I had a few requirements in mind before I try the software.

Criteria For Choosing The Best Freeware Duplicate File Finder For Windows

The software should be a freeware, no shareware, ad-ware or trial version. It should not come with loaded “crap-ware” or browser toolbars. It should not be a “cripple-ware” which asks users to pay to access all features. It should make it easy to find duplicate files. It should not scan for duplicates based on similar file name or file size. It should support external drives. It should scan using MD5, SHA1 or CRC method. This will increase the chances that the files are true duplicate files. Although, not required but if it exports the list of duplicates to TXT, CSV, or HTML format, it’s a plus point for them.

Without any much talks, here’s the list of five best free duplicate file finder software for Windows.

Duplicate & Same Files Searcher

So, don’t judge it by its looks. Its uniqueness is what made it to the top of the list.

Duplicate Commander

Duplicate Commander is a freeware Windows application. It is available both in installer and portable format. It finds duplicate files and helps remove them to the Recycle Bin. Yes, it doesn’t delete the files permanently. If you can live with the odd toolbar icons, you can get it to work properly. Only one relief is placing the mouse pointer on the icons displays a small description. I hope the developer will change the present icons to something better.
