We can detect them and then decide if we want to leave them as they are or if we prefer delete them and free up space.

The advantage of using these programs is that we will get put order on our computer and we will be able to gain many megabytes of storage that we will be able to use in something else, to save files that are not already there. It usually happens to us with photographs that we copy here and there, repeated folders … That is why there are many programs that allow us to eliminate duplicate files in Windows, sort them by size or by date or by name and easily find everything that is left over.


This free program is designed for all those who want to put their photos in order on the computer and do not know where to start.

It will analyze to find pictures with coincidences and we will be the ones who can have the final decision: delete it, leave it as it is … They are not always identical so it is not recommended that it be deleted automatically.
