File shredder what. Software shredders. The trash can is a spy's best friend

Deleted files can be recovered.

In the life of every PC user, there comes a moment when he takes up the "mop" and "broom" and begins to put things in order on his hard drive. Hundreds and thousands of files and folders are irretrievably deleted, some programs are uninstalled, files are grouped and harmoniously lined up in endless spaces hard disk... Having spent a lot of time on this process, you look with pleasure at the result of your work. All that was needed remained - all that was unnecessary was forever destroyed.
This one is, but not quite. Almost all remote files can be recovered, even though you deleted them permanently and not in the Trash. "Why?" - you ask. Because that's how it works file system in MS Windows.

The fact is that when you delete a file through the operating system Explorer windows systems (past the Recycle Bin) the file is not physically removed from the disk. It is only marked as deleted, and the disk space that it previously occupied is marked as free, i.e. ready for recording. But, in fact, the data stays where it was.

This file deletion mechanism is used to build algorithms for the operation of programs that recover deleted databy restoring a record of the existence of the file.

Any phenomenon always has both positive and negative sides... Recovering data from a "failed" hard drive brings joy when this information is returned to you. But when the file that you have deleted falls into the wrong hands, it’s not very pleasant.
To reliably delete a file from the system, it is not enough to delete it through Windows Explorer past the Trash or to the Trash and then from it. Moreover, even after formatting hard disk, data can be partially or completely restored... Therefore, your old hard drive, which you sold or decommissioned, may well become an object of interest for a certain circle of people. Recovering information can be quite expensive and time-consuming, but when it comes to really important information money and time fade into the background.

How file shredder works

To securely delete the file and to be sure that no one can restore it and gain access to the information that you wanted to permanently destroy, you need to use a different approach. This approach is implemented in programs called file shredders (from English to shred - to shred, shred, delete documents).

Such programs work as follows:

  • The content of the file is overwritten, i.e. the disk space that it previously occupied is filled with other data (a random sequence of numbers). Thus, by overwriting some data with others, you really destroy their presence.
  • Then the file is deleted.

There are ways to recover information after such procedures, but this requires special equipment that allows you to record a negligible level of remanent magnetization on the disk surface. This is costly, which is only worthwhile if you kept the supernova fighter plans.

There are various data erasure algorithms. Basically, they differ in the number of passes and the types of data that are written to the erased place. The simpler the algorithm, the less time it takes to work, while the probability of data recovery is higher. But even after one or two passes, the probability of data recovery is very low.

The trash can is a spy's best friend

Obviously, deleting an electronic file in the Trash is like throwing sheets of paper into the trash can near your desk. Filesdeleted windows tools become available to anyone who has access to your computer. In serious organizations, it is customary to destroy all at least a little significant paper using an ordinary shredder, which shreds a sheet of paper and mixes the resulting strips.
Agree, the analogy is obvious. So why not adopt this idea, and not only protect yourself by encrypting the necessary information, but also by reliably deleting unnecessary information? As soon as this question arose, the idea immediately appeared that the Rohos program should not only protect the necessary information, but should destroy unnecessary information and, thus, provide users, that is, you with maximum protection. Which was implemented in latest version

File shredder in Rohos

So, the file shredder - new opportunity in the Rohos program. This means that you can now remove the information you need, and the unnecessary can be safely deleted.

The second pleasant news for you is that File Shredder is installed along with and is integrated into Windows Explorer.


File shredder allows you not only to delete files that you no longer need, it also allows you to move files to the desired location (for example, to another folder, to an external hDD or on a flash drive), and immediately after moving, overwrite information about deleted files... Two actions in one movement is always nice, you must agree :)

Rohos file shredder works as follows.

  1. Select the files you want to move or just delete.
  2. Right-click on the selected files.
  3. Select the sub-menu "Send To". And then click on Rohos File shredder... Rohos shredder window will open, showing a list of selected files.
  4. Specify, if necessary, where to move the selected files and folders before overwriting. It can be another folder, or one created by Rohos.
  5. Select action type:
    a. Copy and overwrite
    b. Only wipe
  6. Click on the "OK" button to confirm the selected action.

Just six actions that will take a few seconds and provide your information "eternal rest". You can assume that you cremated her and scattered the ashes in the wind.

Summary
The summary of this article is pretty obvious in our opinion. If you have at least some significant information, then it must be protected, and the program will help you with this. And if you want the traces of deleted information to be thoroughly cleaned up, and the information itself remains only your property, then you should use the Rohos file shredder.
When it comes to confidentiality, reliability and security, then financial issues fade into the background, and sometimes even the third. This is the reality and we offer reliable remedies against this reality.

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 full news and there download File Shredder , then you will get a tool for permanently deleting any folder and file, and it will be possible to do this with data not only located on the hard disk, but also on removable media. If you read the official description of the developer, then they declare this that, to permanently delete the file, the File Shredder program will overwrite the data with random bytes, as well as the date and time of modification, so it is also able to ensure the secrecy of deleted information.

In general, as far as I can understand, File Shredder uses five algorithms to delete files. In this case, you are asked to make a choice, some of the options can work much longer, that is, not a second or two, but a minute or a few, but you will get rid of the data more reliably, after which it will be unrealistic to recover. After installation, the program can be integrated into the Windows shell and from the context menu it will be possible to mark the file or folder you need and start uninstalling immediately, which will significantly reduce the time. So, to summarize, it is worth noting that File Shredder can not only simply delete files, but also delete them beyond 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 still check for updates to File Shredder from the main window.

Issue name: File.Shredder.2.50
Developer.

Good day, dear friend!

The topic of computer chess cannot be avoided by a modern chess player. Or rather, of course, but the 21st century is outside the window, after all. Today in the epicenter of our attention is the chess program 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-Kalen

The year of the program's birth is 1993. Since then, Shredder has firmly established itself on the first lines of all kinds of ratings.

Shredder is the winner of the championship among chess programs 1996 , 2003, 2010 years. World Blitz Champion 2002, 2003, 2004, 2005, 2007 years. Naturally among the programs.

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.

The latest version of the program is 13 ... Official site

I think this is enough for a general concept. List in detail the titles 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.

Online play

1 ... My first acquaintance with Shredder took place

The picture is like this:

Three levels of play - easy, medium, hard

There is an option: take the move back.

I start at the easy level

I make a few moves. It becomes clear that this is not really 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 play one more game. The same, some kind of ragged method.

He won both games, but overall he is playing well, I would rate it as 2 or even 1 grade.

Medium level

I poured the first batch into one wicket. In the second, I got badly in the opening, sacrificed an exchange for dubious chances of an attack, then I found another tactical trick. The computer suddenly "floated". I won the game.

I came to the conclusion that the program is geared towards obtaining a material advantage. A couple of times I “grabbed” dubious pawns and exchange.

In general, the verdict is this - at the medium level, the engine plays in the strength of a candidate, and maybe a master.

Hard level

At first I thought there was no point in even trying. If so on medium barely carried his feet, then on hardand 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 a dozen games. Try it yourself.

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

The interface is the same, one to one. Much to my amazement at the medium level, I put out the shredder "under the walnut" ... Ditto for easy.

A strange thing turns out: does Schroeder play different strengths on different sites? Or maybe my strength of the game changes with the speed of the car?

In short, the levels of the game were incomprehensible. 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 you can download Shredder to your computer.

Installation on a computer

The full version of the program is paid.

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


Downloaded and installed without problems. Russian interface! Fine.

Yeah, that's the catch. Give 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 straightforward. In their native language, after all.

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


First I asked 1800 (I have about 2300)... I 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 said, the impression was that the Shredder at the middle level plays in some kind of ragged rhythm - a series of strong moves, then weak. Plus can view tactics, which is rather strange for a computer program.

However, I think it is better for you to try it yourself, my opinion may turn out to be too subjective, and maybe even erroneous.

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

Useful options

File tab

  • Position editing
  • Commands Tab

    • Offer a draw. In the online versions we started with today, it's impossible to offer a draw. We have to use the position to the naked kings. It is very uncomfortable.

    Levels tab

    • Time control setting. Choose standard blitz controls or set control yourself.
    • About the limitation of strength, the choice of rating I have already said above

    Mode tab

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

    For example like this:


    Or even like this:


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

    I did not set such a goal for myself and in this context I will refrain from giving advice. Because your humble servant is a chess player and is ready to advise only where I understand.

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

    I suppose that just admins set different levels in the program itself ... For example, on one site the medium level plays on the installation of the program 1800, on the other - 2200.

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

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