Find duplicate files through the program

Unfortunately, none of the users of computer systems is immune from the periodic occurrence of situations associated with the appearance of files not only with the same name, but also a uniform extension. Search for duplicate files should be performed in the system at different intervals. But not everyone knows what is needed for this.

Why do duplicates appear?

To begin with, it should be noted that the appearance of files in the computer system with the same name and extension can be associated with a variety of reasons, and not all of them, as some users believe, can be critical. Here the problem is that many applications create their own temporary files during the installation , after which they can be deleted automatically or in manual mode.

Unfortunately, not all users know that in the program directories after installation of any other application there appears a file of type Uninstall.exe or a file having a different name or even an extension (Uninstall001.dat).

Nothing wrong with that. Such components are responsible only for uninstalling the installed application and are deleted automatically after the process is completed. In an extreme case, the remnants can be removed manually.

Internet surfing

The surfing problem in the World Wide Web is quite common. The point is that any browser used in the system saves temporary files and links in the cache. Of course, not every user knows how to get to them, for which they are needed at all. However, any program for finding duplicate files will be able to find such data even in those places that ordinary users simply do not guess.

You can clear data using your own browser tools or applications designed to optimize the system. But they often do not justify their purpose.

Installing programs

Of course, the installation of software products leads to a general clogging of any computer system. This is due to the emergence of temporary, and then - and uninstall files. The situation is that some of them are deleted immediately after the installation of an application, while others remain in the system.

Now you need to clearly understand how to search for duplicate files on your computer. Actually, "operating systems" such as Windows or Mac OS X own funds for this have (with rare exceptions, relating to "poppies"). The principle of operation of all applications is not based on the search for names of the same name, but on the comparison of so-called checksums. This will be discussed a little later.

Troubleshoot problems manually

Naturally, looking for the same files or files with the same extension, even on systems like Windows 7 or 8 - it's absolutely ungrateful. Not only will it be necessary in the search to enter the name of the file and its intended extension, so also the search will take so much time that not every user will be able to endure. It remains that? Yes, only one - to use at least the search for duplicates of files Windows 7 or the own funds of the "eight", although it does not shine.

In principle, neither standard nor specialized means of eliminating the problems associated with finding duplicates, do not differ. Consider the most popular of them.

Applications for finding duplicate files

Let's talk at once: not every program for finding duplicate files is able to recognize whether this component is needed in the system. Especially it concerns dynamic DLLs, accompanying drivers and extensions that are responsible for their work.

The easiest solution is to install the "easy" Duplicate File Finder application. Naturally, the program will find duplicates, but no user can be immune from the fact that from the report provided by the application, will remove some system components, and this can lead to a complete "crash" of the entire system.

How it works

Search for duplicate files and folders is carried out using several basic algorithms. Firstly, names and formats are considered. For example, the search for duplicate audio files occurs first by the principle of comparing ID3 tags. If such lines are not filled in the information fields, the comparison of audio can be performed according to the principles offered by the tools such as TrackID for mobile gadgets, which analyze the sound of the song, and then give out full information about it.

It's not even that. Just the compositions that have the same "trimming" can differ in the time of sounding, in the quality of the reproduced material, etc. But the checksums and characteristics of the file itself in the formats .mp3,. Wav, .ogg, .aiff, or .flac remain unchanged. It is on this basis that two identical files are cracked, which can duplicate each other. Separately, it should be noted that sometimes the situation with duplicate audio can also be related to the fact that first, for example, one track is downloaded, then an album or a selection of music in which some composition may be present, etc. Note that this It does not concern at all the variations of the type of remixes or compositions that are recorded in such now fashionable performance as feat, vs or tribute to. Take at least this option: King Diamond. Tribute to Metallica. One group simply performs the compositions of the other. Duplicate search programs let things pass by.

It should also be taken into account that for the most part such applications are designed only for searching, and certainly not for removing duplicates of multimedia files available on the hard drive.

On the other hand, it is worth noting and the fact that the same search for duplicate files in Russian can be done automatically even with the specified key interface language. In any search string it is enough to enter the name of the file or a part of it.

With extensions worse. The fact is that no program that searches for duplicate files on a disk or removable device can interpret the same "ex-file" file (.exe) in the sense of similarity to another.

The simplest example is the usual Setup.exe installation distribution. It is clear that in the presence of any number of such files, they still differ among themselves.

Why do I need to find duplicates

Now, perhaps, we will pass to one of the most serious sections. Why do you think you need to clean the system of some files and their copies? Yes, everything is simple. The fact is that when you open a particular file, the system, even when determining the location of the file on the disk, refers directly to the entry in the system registry, which is responsible for the object being opened. If there are several such objects, and even more so, the records about them are different, the system will start to "think", although it is not peculiar to it. This "reflection" often ends with either an incorrect completion of the application itself, or a problem with the inoperability of the entire operating system as a whole.

System Cleanup Programs

Universal packages that purge the system of "garbage" are also not always able to recognize certain files with the same names and extensions. This is especially true for system files, for the removal or relocation of which the program simply does not take because of its capabilities.

It's better to approach the problem, armed with professional utilities. One of the most interesting is the CCleaner program, which, when tested, can stop even some system processes. About the mobile application, you can say that this utility is able to even block some programs installed on the gadget. In this case, the search for duplicate files when connected via the USB interface is no different from the standard process. You can use some specialized programs to synchronize your mobile device with a computer terminal such as My Phone Explorer. However, such applications, for the most part, can not search for duplicate files and folders.

What's better?

Now it's time to get busy with the programs responsible for finding duplicate files. First, install the Driver Sweeper application.

Believe me, it's worth it. This is a search engine of obsolete or unused drivers in the system. Do not be surprised that the program will offer to "demolish" some native drivers such as Intel Audio or auxiliary drivers for video cards such as nVidia or Radeon.

Nothing wrong. The same search for duplicate files Total Commander can produce no worse (but not better). The standard features of a file manager or specialized utility often simply do not meet the user's requests. That's why you have to rummage on the Internet, "shovel" a bunch of websites with suggestions for installing a particular utility, and so on.

In fact, getting rid of such a headache can be quite simple. The best program for finding duplicate files, according to many experts, is DUPEGURU.

In general, since it came about this application, it is worth noting that the program is quite rare and completely unclaimed. But in vain. In fact, this application is able to perfectly understand and with numerous multimedia formats. For a complete package, you need to install additional versions such as Music Edition and Picture Edition, after which any user will have the ability to automatically recognize music and pictures, and at the same time and remove the same data.

Optimization problem

Of course, the problem, which involves finding duplicate files, does not stop with this solution. It is clear to any user that the use of a special utility oriented specifically for this process will avoid many difficulties, for example, with the optimization of the operation of a computer or laptop.

Actually, the very reason for the slowdown can be found in incorrect or obsolete system registry links, and they, as you know, appear even when creating a backup (usually a file cc_year, month, number with .reg extension).

Perhaps work with the system registry and it seems very difficult, however, the removal or transformation of some links and entries will affect the entire system completely painlessly. This applies to some sections of the type HOT_KEY_LOCAL_MACHINE or HOT_KEY_CURRENT_USER. You can change anything here. In some command lines, you can even specify an automatic refusal to assign a direct call command to the file. Roughly speaking, this is a change of the symbol "0" to "1" (the usual inclusion of any function). However, it is better not to experiment with this.

This is understandable. Even finding or removing some of the same configuration files can lead to the most unpredictable consequences. Everyone knows that even in the "native" Windows folder there are files with the extension .sys, and in the system of such files one can find such an incredible amount that no program will determine whether a file is needed in the system, whether it is a virus, etc. .

Conclusion

It remains to add that the search for duplicate files by these methods is not limited. Everyone is free to choose which program to use. Some even do not trust third-party software utilities, preferring to delete information using primitive tools. It does not matter. The main thing is that the maximum effect is achieved.
