Chess program shredder. File shredder. Secure file deletion File shredder for deleting files

Storing confidential data on your hard drive and removable media, as a rule, is always considered in the context of the general information security. This is a fairly voluminous topic, covering many different aspects, not the least of which is secure file deletion.

There may be several reasons for this - transferring a computer, disk or flash drive for temporary use to another person, handing over a computer or media for repair, as well as selling them. Simply deleting data using the operating system or even completely formatting the media does not ensure permanent deletion of information.

In most cases, deleted data can be recovered using data that can be easily found on the Internet. One hundred percent guaranteed destruction of data can only be achieved by demagnetizing the media or its complete physical destruction. These are the measures that are taken in relation to data stored under the heading “Top Secret”. To destroy data of a lesser degree of secrecy, utilities are used that use algorithms for repeated rewriting of the entire media or a specific area of ​​it.

Currently, there are many programs for safe removal data. There are just as many opinions regarding the effectiveness of this or that utility. In reality, claims that one shredder program deletes data better than another is nothing more than a myth. It is not the program itself that deletes information, but the rewriting algorithm built into it, and these algorithms are the same in all these utilities; it’s just that one program may have a wider range of algorithms than another. According to experts, Peter Gutman's algorithm, which uses 35 rewrite cycles, is considered the most effective. Here is a small list of utilities that will help you to ensure that your personal information is deleted.

CCleaner

This popular free cleaner can be used not only to remove file junk and fix errors in system registry, but also for guaranteed formatting hard drives and removable media, as well as clearing free disk space. In this case, four deletion methods are available: simple overwriting in one pass, DOD 5220.22-M (three cycles), TSA (7 cycles) and the Peter Gutman method already known to us.

Eraser program

Simple and free program for secure data deletion. With its help, you can delete not only individual folders, but also entire partitions, as well as clear free disk space. Despite the lack of Russian language, using the program is very simple. Deleting files and folders is done by simply dragging them onto the Eraser work field; in addition, you can delete objects from context menu Explorer, where the program is embedded during installation. There are 14 deletion algorithms to choose from, including the most reliable - Peter Gutman's algorithm.

File Shredder

Another one free utility, simple and convenient. Deleting data from and also from removable media is supported. Adding files to the list to be deleted is done through the main menu, or by directly dragging onto working window programs. File Shredder can also be used to wipe free disk space. It is also possible to delete through the Explorer context menu. Unlike Eraser, File Shredder has only five built-in deletion methods.

Secure File Vault Program

Multifunctional protection program confidential information. Intended this application mainly for data encryption, but can also be used to permanently delete files and folders. Secure File Vault has a built-in File Shredder utility for this purpose. When deleting data, you can choose a security level from 10 to 110. Secure File Vault is a commercial program, and quite expensive at that - its cost is $49.95.

Freeraser

Free, simple and convenient program for removing any user files with Russian language support. There are three main removal modes available in Freeraser - fast, reliable and uncompromising. Fast corresponds to one rewrite cycle, reliable – to three, and uncompromising – to 35 consecutive passes. and folders is done by dragging them onto a special trash can from the standard “Browse” window. The utility supports configuration appearance baskets, autostart, work from the system tray. Russian language available.

Conclusion

All five of these programs, on the whole, do their job very well. If you want to be sure that your personal files cannot be recovered, then use any of these programs. Of course, this list is far from complete; many utilities for secure data deletion are included in other programs, as is the case with Secure File Vault. Built-in stripping tools include AusLogics BoostSpeed, Acronis True Image, TuneUp Utilities, and many other applications for working with the file system.

Among the five programs described above, we decided to give Eraser first place. This program undoubtedly deserves to be called a professional tool for effectively destroying confidential data.

The rewriting methods used by the program are based on the most well-known standards for removing magnetic traces from hard drive and removable media.

Wide range of tools flexible settings, the use of additional “deceptive” technologies, as well as a friendly user interface make this program one of the most convenient and popular tools for securely deleting files.

Good day, dear friend!

There is no way for a modern chess player to ignore the topic of computer chess. More accurately, it is possible, of course, but the 21st century is outside the window, after all. Today, the epicenter of our attention is the program for playing chess shredder.

What is this program?

The correct name of the shredder is " Shredder", or Shredder– a chess engine developed by a German specialist Stefan Meyer-Kahlen

The year of birth of the program was 1993. Since then, Shredder has firmly established itself on the first lines of various ratings.

Shredder - winner of championships among chess programs 1996 , 2003, 2010 years. World Blitz Champion 2002, 2003, 2004, 2005, 2007 years. Among the programs, naturally.

Shredder is a standalone chess engine that has its own graphical interface. The Shredder engine can be installed on other graphical interfaces, For example, Arena.

Latest version of the program – 13 . Official site

I guess for general concept It's enough. List in detail the names of the championships where Shredder won , - no need. We are more interested in how it can be “used”, how convenient and suitable it is for our level.

Play online

1 . My first acquaintance with Shredder took place

The picture is like this:

Three levels of the game - easy, medium, hard

There is an option: take the move back.

I start with the easy level

I make several moves. It becomes clear that this is not entirely “easy”. The program makes a series of pretty decent moves. Then the truth makes a mistake. And so on until the end of the game. I'm playing one more game. The same thing, some kind of ragged method.

He won both games, but overall he plays well, I would rate him at 2 or even 1 category.

Medium level

The first batch was poured into one gate. In the second, he got a bad opening, sacrificed an exchange for dubious chances to attack, then another tactical trick was found. The computer suddenly floated. I won the game.

I concluded that the program is aimed at obtaining material superiority. A couple of times I grabbed dubious pawns and exchanges.

In general, the verdict is this: at the medium level, the engine plays as a candidate, and maybe even a master.

Hard level

At first I thought there was no point in even trying. If so medium barely carried his feet, then on hard and there is nothing to catch.

However, to my surprise, Shredder plays at about the same level on hard as on medium. However, for a more accurate assessment it would be necessary to play about a dozen games. Try it yourself.

2 . For the purity of the experiment, I decided to test Shredder on another site.

The interface is the same, one to one. Much to my amazement, at the medium level I took out the shredder "under the nut" . Same thing for easy.

A strange thing happens: Does Schroeder play at different strengths on different sites? Or maybe the strength of my game changes with the speed of the car?

In short, there are still some confusion with the game levels. The answers were found when I downloaded the program to my computer.

But this is not the main thing. Too primitive interface and few options . And I decided to look for where I can download Shredder to my computer.

Installation on a computer

The full version of the program is paid.

In order to evaluate the capabilities of Shredder, you can download the shareware version. I downloaded . It is called Shredder Classic 3

It downloaded and installed without problems. Russian interface! Great.

Yeah, here's the rub. Granted 30 days trial period. Free trial. What will happen after this period, what options will remain and whether the program will work at all is still unclear.

The interface is quite friendly and understandable. In your native language, after all.

I immediately found what I wanted. Namely, the ability to set the level in numerical terms. Like rating:

To begin with I asked 1800 (I have about 2300). Played a game. Plays approximately at the level of this rating. Perhaps even a little stronger than real players with such a rating. It seemed so.

As I already said, I got the impression that Shredder at an average level plays in some kind of ragged rhythm - a series of strong moves, then weak ones. Plus can view tactics, which is quite strange for a computer program.

However, I think it’s better for you to try it yourself; my opinion may turn out to be too subjective, and may even be wrong.

I'll briefly go over other possibilities. Shredder Classic 3, which seemed the most interesting and useful:

Useful options

File tab

Commands Tab

• Offer a draw. IN online versions, with which we started today, it is impossible to offer a draw. We have to use the position to bare kings. It is very uncomfortable.

Levels Tab

• Setting time control. Select standard blitz controls or set up controls yourself.
• I already said above about the limitation of strength and the choice of rating.

Mode Tab

• Possibility of position and game analysis
• In addition, you can change the interface settings: the shape of the pieces, the design of the board, and so on.

For example this:

Or even this:

If you wish, you can download more advanced versions of the Shredder program. Through torrents or something else.

I have not set such a goal for myself and will refrain from giving advice in this regard. Since your humble servant is a chess player and is ready to advise only what I understand.

Yes, I almost forgot. Why does the shredder play with different strength on different sites?

I guess that it’s just that the admins set different levels in the program itself . For example, on one site the medium level is set to 1800, on another - 2200.

So, for a comfortable game, you will also have to select a site with Shredder settings that suit you.

Hence the conclusion: It’s much easier to download the program and use it, as they say, with all the conveniences.

Recently, another free program was updated, which was created specifically for cases when you need to reliably get rid of information. So, if you decide to go to the full news and there download File Shredder, then you will receive a tool for permanently deleting any folder and file, and this can be done with data not only located on the hard drive, but also on removable media. If you read the official description of the developer, then they state that, to permanently delete a file, File program Shredder will overwrite the data with random bytes, as well as the modification date and time, so it can also ensure the secrecy of deleted information.

In general, as far as I could understand, File Shredder uses five algorithms to delete files. At the same time, you are asked to make a choice, some of the options may work much longer, that is, not a second or two, but a minute or several, but you will get rid of the data more reliably, after which it will be impossible to restore it. After installation, the program can be integrated into the Windows shell and from the context menu you can mark the file or folder you need and immediately begin deleting it, which will significantly reduce time. So, to summarize, it is worth noting that File Shredder can not only simply delete files, but also delete them without the possibility of recovery, you will get five algorithms for work, there is integration with Explorer, files and folders can be deleted simply by moving them to the main program window, You can also check for updates for File Shredder from the main window.
