VOVSOFT - Duplicate File Finder

A lot of people end up storing the same files in multiple locations, either to ensure they have several backups in case one fails, or by accident.
If you want to make sure you do not fall in the second category, you can try VOVSOFT - Duplicate File Finder.

Simple, no-fuss GUI

The main window is as straightforward as it gets, and you can easily add one or more folders to be thoroughly examined.
Also, you can narrow down the scope of the analysis by creating a file mask, so that VOVSOFT - Duplicate File Finder only processes the type of files you are interested in. However, you cannot exclude a sub-folder from the search, so all the data is inspected.

Supports several search methods

Despite being such a simplistic application, this tool offers you the possibility to choose the type of duplicate search that best suits your needs. More specifically, you can have the app analyze only the name of your files, yet you need to keep in mind that this method is the most likely to trigger false positives.
Alternatively, the software solution can take a look at the size or the contents of the files - these methods are bound to yield more accurate results, yet they also take more time to complete.
Regardless of the option you went for, VOVSOFT - Duplicate File Finder displays a list with all the items that match your criteria and a different one with the results of the search. When accessing the duplicates list, you can easily mark the ones you no longer need and send them to the Recycle Bin with a single mouse click.

To sum things up

All in all, VOVSOFT - Duplicate File Finder is a quick little app that can save you the trouble of manually looking for dupes within your data.
