One way to secure a  file  in Windows is to make a copy of the  file  . Not infrequently, we do this copy  more than once on our operating system. This activity is fairly normal, because it includes the data backup  step  . Some of us even put a  copy of the file on a folder or even a disk different from the location of the original file . If the original file  has been used and we don’t need it anymore, of course  the we will immediately delete it. However, what do we do with  the files we’ve copied?

We tend to just ignore them. Likewise, when we  download files many times on  the same link  . Generally,  the second file  will name itself with the addition – Copy. Indeed this is not a big problem. However, if we do it often, then of course it will accumulate unnecessary data. Plus the data is no longer needed. Of course the thing we have to do is delete it.

However, the question arises, what happens if the copy of the file is too much and we have forgotten to put it on which folder or disk? The easy way is to download the Duplicates Cleaner application.


As the name implies,  duplicate cleaner,  is a Windows  program  that is intended to find  duplicate files  and  folders  to be deleted later. All types of files  can be scanned and deleted, including looking for  image files  with similar images even after editing . This application itself can be on Windows  versions 10, 8, 7 and even Vista,  if you still have a device with Windows Vista.

7. To be able to delete a file,  check the  file  . For example, the author wants to delete a  file  with module 8 in  the DEBIAN MODULE folder  , because the contents are the same as the  file with the same name, namely Module 8 in  the Word File folder.

The app at a glance offers the same thing as the search method featured in Windows Explorer. But keep in mind, the application displays the  file  being searched for with various types of data display fields. Plus the search process makes it easier for us with extension choices and a fast process. We don’t need to remember the file  name  and extension that was duplicated first.
