Duplicated files finder

How often do you find your PC disk looks like trash? Often there are multiple copies of same file, in different folders, under different names.. This application helps get rid of this mess. It does not do any thing with your files on its own. It shows you which and where duplicated files are.

Modes of operation

There are 2 modes of operation. Two side search and multiple side search (any to any)

Two side mode

In this mode 2 folder sets are defined. Application reports those files which are present in both sets.

Any to any

In this mode there is only one folder set. Application reports files present in the folder set at least twice.

Equality criteria

There are up to 4 equality criteria used.

  • Size of file - this criterion is applied always. Of course duplicated files must have equal size
  • Time - if applied only files with equal last edit time are reported.
  • File name - if applied only files with equal file name are reported.
  • Content - if applied only files with equal content are reported. Please note application does not analyze content of files, so if you rotate or resize an image then the application will not report it as duplicate of original one.
The application can look into unprotected zip archives and find duplicates inside of these archives if additional file unzip32.dll is present.

Folder set

Depending on mode of operation one or two folder sets are used. In the folder set there are listed folders where to search for files. They may be on different discs. Inside of listed folders there might be subfolders where duplicate search is not needed. These are exclude folders within folder set. For example, whole C disc is included, but we do not want look for duplicates in recycler and temporary internet files.


  1. Choose mode of operation
  2. Make folder set(s). Click the button with green hook to include a folder and with red cross to exclude.
  3. Select if we include zip files' contents and a minimum size of files to look for.
  4. Click GetInvent. It might take a while for application to make candidates list and depends on files quantity in the folder set(s). So, the size criterion is already applied. The numbers in the candidates list are representing number of found duplicates candidates. Click on an item in candidates list shows in explore list the list of actual files.
  5. Apply additional criteria reducing candidates list. The content criterion is very time consuming, but after it finishes only true duplicates are remaining in the candidates list.
Tip. If content criterion is applied but not file name criterion then real duplicates will be reported even they might have different names.

The user interface

The application's interface language in current version is Latvian, but here is its translation.

System cleaning When working with zip files application might create temporary folder for its temporary files. Normally on exit application deletes them. But if application has been killed by task manager or PC has hanged, these files might remain. In this case go to your temporary files folder and delete subfolder(s) which names are starting dubliq
