These Tools help to find duplicate data, empty files or empty directories.

Then the software delete the not needed things



Duplicate Cleaner Pro

Dear team, see this review of your program on a known website.

What is good?
Duplicate Cleaner Pro is able to select the files for deletion itself, based on different criteria, like length filename, path, age.

As opposed to many other tools, it is able to select arbitrary all duplicated files except one.

It still struggles with selecting arbitrarily duplicated folders.
The typical use case are different copies/backups of program folders. In my case I regularly take backups of all installed programs and program folders for installation. I also use portable apps.

When there was not change in the program version, very often there are folders that are absolutely identical.

When I now compare my backup of portable programs of May 2020 and the ones of March 2021, only some folders have changed, namely the ones where A) I installed a new version or B) the ones that contain some cached data.

Beware that the current selection possibilities solely based on files are not sufficient.

see also this ticket here.


Step1b: Search Criteria: Scan location

Choose the folders that are protected; files in this folder will not be deleted.


A) Main photos protected,

B) Data, SyncPhoto and SyncTeam are protected.

Step2: Mark by location

Duplicates Backup folders or input folders can be deleted, we keep only the main folders

  • Choose Scan Location: Protect certain folders where one should not delete
  • Choose Scan Location: Protect certain folders where one should delete

Example: Mark for deletion


Z:\Doc\MyPrivate\Job\!Job In
Z:\Doc\MyPrivate\Job\2013-2018 IET\!IET 2013-2020 from Mail
Z:\Doc\MyPrivate\UBS\!2018-2020 UBS from Mail
Z:\Doc\MyPrivate\Invest\3a\Viac\Geo\!Documents Viac In

Step2b: Delete the files

We use the File Removal function. we mark “remove empty folder”.


Step3: Duplicate Folders

For Duplicate Folders we typically choose one folder that remains in arbitrary way.

and again choose 3b: File Removal

This is typically used for software folders, same software in many places, or their subfolders.


Step4: Mark by Text Pattern

Duplicate files often contains patterns like:

  • Copy
  • (1) or (2) or (3)

4b: File Removal

during the file remove process, you will encounter this warning message.
Usually one presses No here.

Unfortunately you need to continue manually and find folders that would be erased completely.

You may continue with another pattern.


Press No and  unmark the pattern or press on unmark all.

You can continue with the following steps.



Step4: Mark by Smallest Files for deletion

In rare cases one can find duplicates with a smaller size.

and delete them via File Removal

Step5: Mark Longest Folder Names in each group

If  you have ordered files into subfolders, you might use the option “Mark Shortest Folder Names”

We usually use the longest folder names, given that duplicate folders were create

Step6: Mark by created date/time

Choose Newest files in each group for deletion



Why newest files: When duplicate files are created, they obtain new time stamp.

This can happen when taking a picture.

Step7: Mark by modified  time. 

Similar to Step6.

Step8: Mark by Group

Mark all but one
