Duplicate File Finder Mini is a 100% freeware that used to fast find and clean the large (1 MB+) duplicate files on all your hard disks and removable storage devices, so as to recover your valuable disk space.

It works very fast, usually, doing a fully finding only spend a few seconds depending on the size of your drives (about one minute per 300 GB files). Moreover, it's easy, you will get you wanted just by clicking the "Find Now!" button.

The result will be shown instantly after a finding done: sorting by size in descending, marking the adjacent duplicate file groups by different colors, showing the name, path, size (MB), type, date modified of all files, just for operating them conveniently.

And you can do some common actions for the checked duplicate files / highlighted file in the result listing, such as Save, Load, Move to Recycle Bin / Other Place, Delete, Open/Run, Open File Location, Find, Uncheck All, Invert Checks, Show Properties and Copy Full Path. Sure, you can use some options (e.g. whether scan the system / hidden files and exclude the system / special folders or not) to affect the final result.

Please note that it is not only used to save your disk space, but also reduce the management costs and avoid the unnecessary confusion via found and deleted the redundant duplicate files.

At last, two matters needing attention: 1. Only large files would be scanned (1 MB+), because the normal PC users don't care about the small files which can only recover a little disk space. 2. The Mini edition compares files by size, not file name or last modified date. And it does not compare the file contents, however, for the large files, it can ensure the most duplicate files are right, but not 100%, so, please carefully remove the very small part of the uncertainty duplicate files.

# Link Code

As you see, it is very easy to use, just click the <Find Now!> button to get the result (large duplicate files) with fast speed.

Once done, the result will be shown automatically, and you can do some actions by clicking the toolbar buttons or the context menu items for the checked duplicate files / highlighted file. All the toolbar commands have tooltips and shortcut keys.

All things are very simple, just try it, and it is 100% FREE.

# Important tip for scanning scope:

As you see, on the start interface, the "Scan All Hard Disks & Removable Storage Devices Except Operating System Drive" option is selected by default. Why? Because: 1. System drive already has some duplicate files by default, such as some DLL files. 2. Mistakenly deleted the files in system drive may cause the Operating System or some software cannot work properly.
So, even you scanned system drive, we still recommend you do not delete the duplicate system files (such as .DLL, .EXE, .OCX), except these files are not located in the system folders (such as Program Files, Windows, Application Data).

# Here are some important operations, FYI.

Load Result (*.D2FM) on the Start Interface
Click the <Load> button (bottom left, first).

Set Finding Options (About Hidden / System Files, Excluding System / Special Folders)
Click the <Options> button (bottom left, third).

Only Retain One File for All Duplicate Groups (Clean All Others)
Check the needful file for each group, and then click the <Invert> button to invert the checks, at last, click the <Delete> button to delete all other unwanted files.
Tips: you may need to change the filter to see fewer files.

QuoteFind large duplicate files and delete them from your computer in order to gain valuable storage space with the help of this intuitive application

In order for your computer to run smooth, besides protecting it with and antivirus, a good idea is to use cleaning applications, such as this duplicate cleaner free. You can quickly scan the computer and any attached storage devices for files of the same size and remove them to get more precious space.

Compact and easy to use

The main window of the application is pretty small, but manages to squeeze in everything you need to work with. Most space is taken up by rather unnecessary buttons that either let you spread news about the application over various social network sites, or take you online for various reasons.

Luckily, the "Find Now!" button captures your attention from the start, so you clean the computer as soon as possible. There are two scanning options available, one that includes every storage device, and the other same as above except the drive where your operating system is located.

This makes it pretty easy to use, but a more thorough selection method would have come in handy, as you can get stuck with no result if only working with one partition.

Quickly find duplicate files and clean them

Hitting the big "Find Now!" generates a result in a matter of seconds. A new window is brought up where duplicate files are enlisted, and sorted by default according to size in a descending order.

In case you are unsure whether to clean a file or not, you can open its location or run it to see what it's all about. By default, all files are left unchecked so you don't accidentally clean any file that could damage your computer if removed.

To end with

Taking everything into consideration, we can say that duplicate file finder free gives a helping hand in cleaning your computer and freeing up a little more space on your hard disk drive. It can only detect files larger that 1MB, but it does a pretty good job. In case you need a little extra space, or just consider it's spring cleaning time for you computer, give this little utility a try.
