Hello, dear ones. Remember, in your green website-building childhood ( whole year ago) I already recommended and described to you program for searching and deleting identical photos? So, it was an excellent program, but it was paid (although the solution to this problem can be found quite easily on the Internet). And here I also described the program in order to find and delete duplicate files . Damn, it's paid too! 😯
Today I will correct myself - I will describe to you a free and quick program to search and delete various copies of files on your computer, of which you have a lot. They sit quietly in the corners and giggle at you, increasing the size of the disk, slowing down the system (after all, scanning files is vital for its normal operation and goes almost constantly), simply littering the computer with unnecessary load, complicating defragmentation process…
Duplicate files needs to be deleted and we will do this now. Naturally, I will describe everything step by step and in pictures, with all the nuances. And of course, I will give you two versions of the program - the regular one from the official website and the portable one.
Auslogics Duplicate File Finder is a free program for finding and removing duplicate files
Don’t even doubt it – there are duplicate files on your favorite computer. The nature of their appearance has not yet been studied by scientists. Over time, they grow like mushrooms, appearing out of nowhere... Of course, this is a joke - we create duplicates ourselves, without even noticing it. Let's get rid of them already. To begin with, of course you need to download the program.
As promised, here are two versions for you - everyone has the right to choose the one they need, but I highly recommend choosing the portable one. The fact is that in the standard version they will push (or try) an additional toolbar into all browsers - do you need it? For example, no matter how hard I tried, I still caught him - I barely got rid of him. (How? And like this.)

We choose what exactly we will search for, or rather, what types of files will be searched from...
If you are not very versed in the system, I do not recommend choosing the first, top item. The fact is that the system itself uses many identical files and places them where it is more convenient and faster for it to get to them - such duplicate files are not only not recommended to be deleted, but categorically bad!!!
To be on the safe side, create a restore point...
Here are my duplicate files. That's not all - I already found and deleted more than 300 MB during my first acquaintance with the program (I didn't just take screenshots).
