How to delete deleted files. How to remove any unnecessary files on your computer

The notion of "memory" as such is inherent not only to man: computer hardware, for example, is equipped with a storage device (HDD, SSD), whose functional capabilities are primarily designed to record, store and manage the data. After a certain time, free space on the hard disk becomes less and the user just has to erase some information. Most likely not everyone of you thought about how to delete deleted files. Nevertheless, the actual nature of the matter requires detailed consideration. After all, the "Delete" button used only creates the illusion that the erased information is destroyed, in fact everything stays in place ... The presented material will help you answer a number of questions concerning the multifaceted process of removing various files from the computer hard drive.

How does this happen?

The file system changes only the attribute previously assigned to the remote file, and in the future (actually filled) the disk space can be overwritten. We will not go into technical terms and touch on the first part of the question of how to delete deleted files. To do this, we resort to a simple example: you must have paid attention to how quickly the file is erased, which, by the way, has a considerable "weight", say, 100 MB. However, the process of copying to the hard disk of the same amount of data takes a relatively longer period of time. All because before you get on the HDD, the file is given a name, and the necessary space on the disk, of the appropriate size, is reserved. Then the system reads data from the storage medium and, following a certain algorithm, copies them to your hard drive. It is worth noting that the retention rate (the recording process on the HDD) can be radically different from the same action performed on other hard disks. The reason for this in the first place are: the type of drive, poor readability of the drive (drive), memory wear and other factors affecting the process as well. But the second part of the question is solved, paradoxically, by the same method of recording, however, somewhat in a different form.

How to delete deleted files: a specific solution

That's why the hard drive's performance is so high - the system does not take the time to completely erase the erased information. All that Windows does is put the "attribute" of the remote in the file attribute, that is, it makes the disk space for subsequent recording free. However, seeing the unreliability of this method of "recycling", it is worth remembering that if you erase personal information in a standard way, it can always be used by intruders or ill-wishers, by simply restoring unreliable "buried" data from your hard drive. However, we run a little forward ... So, in order to delete the information irretrievably, it takes several times to overwrite that area of the disk in which the unwanted file is located. And not just clogging clusters with new data or zeroing sectors of HDD, and confusing the way of finding (markers of definition) of "rejected" zeros and ones, having resorted to complex renaming algorithms.

From theory to practice

With the decision of the question "how to delete deleted files", you can be helped only by specially created for such operations shredding programs (the English word is translated as shred, crush, in general, destroy). But the variety and specification of the application of these utilities are not always "benevolent" in the understanding, and some of them are not very practical to use. Therefore, given the fact that you are not a secret agent, it is prudent to use one of the two methods below.

Option number 1: "insanely" reliable

In the case where you sell someone your old hard drive or just decided to say goodbye forever to an obsolete drive, it's wiser and easier to prevent yourself from unwanted information leakage.

• Download the utility "Darik's Boot and Nuke" from the official site.
• The boot image can be written to flash media, CD or DVD-ROM.
• Of course, the program works from under DOS.
• You will be offered six ways of cleaning. It is advisable to use the third of the list: DoD Short.

Option number 2: file shredder

"And how to delete unnecessary files irrevocably, without resorting to the total method of" large-scale stripping "?" - Perhaps you will ask. In order to erase all signs of the existence of "unwanted data", install the free program "Eraser", then follow the instructions:

• Use the "Erase Schedule" tab.
• Click on the "triangle" icon, select "New task" in the drop-down menu. Or just press Ctrl + N.
• Now specify the directory in which the "applicant for the elimination" is located. This is quite easy: activate the "Add Data" button.
• Now use "Browse ..." in front of the "File" checkbox. And select the file to delete.
• In the initial window of the program, right-click on the directory you specified.
• Now, having resorted to the command "Run Now", you will erase the data "without the right" to restore.

Knowing how to permanently delete a file is definitely useful. However, it is extremely necessary for the user to know about other ways of freeing up the available storage space. Perhaps, we will begin.

Basic Removal Methods

Built-in cleaning tools Windows allow us with you with some comfort to perform operations to "recycle" data that have become uninteresting for us, and to some extent just distracting material. The basket is an integral part of almost any OS, whether it's Win or Mac OS. How to delete a file ceases to be an issue if there is an icon on the monitor screen that resembles a tank, a tank or a different waste container. Nevertheless, sometimes the user has a desire to delete some files, but, strange as it may seem, there is no possibility, since not everything can be subjected to the destruction process, and a "caring system" prevents us from doing this, especially when it comes to OS components.

SyS-extension limits us to something?

In the struggle for free space, the user can afford to disable some OS services and even remove non-critical components of the system. Nevertheless, before anything can be done, it is necessary to understand the possible consequences of their, sometimes ill-considered actions. The question "how to delete a SyS file" is solved in different ways. However, not everyone knows that by sending the system component to the shopping cart, the user can deprive himself of the pleasure of listening to music, watching videos, enjoying the full operation of his own OS. After all, the drivers also have the SyS extension. Another question is when we want to "cut down on the credentials" of Windows, in order to prevent the system from using disk space at its discretion:

• The pagefile.
• Hibernation mode (hiberfil).
• Configuration of the system (config).

For example, by deleting a paging file, you must understand that you will only have to count on the RAM. And if you have RAM will not cope with the current tasks, you will just "hang." If you turn off data backup for sleep mode, you can not use the hibernation function. In general, first of all you can do harm to yourself. And yet, how to remove unnecessary files (if you really believe this) for the sake of saving space on the HDD?

When RAM is in abundance

If your RAM copes with the "obligations" assigned to it, you can delete the file pagefile.sys:

• Go to the "Control Panel".
• Find the "System" icon.
• On the left side of the interface, click on the item "Additional parameters".
• In the window that opens, in the "Performance" section we press the "Options" button.
• Then activate the "Advanced" tab.
• Now click "Change".
• At the top of the window, select the system disk.
• Then put the marker on the "No swap file", in front of this item, click on the "Set" button.
• Completion: "OK".

After restarting the pagefile.sys will be deleted.

The file that is open

Perhaps you were faced with a problem when you could not delete a picture, video or text. All this is because the OS blocks operations with open files. You probably watched the video and forgot to close the player or the text editor, which used the "applicant for destruction." In the case where the question "how to delete an open file" torments you and does not lend itself to logical resolution, you must complete the corresponding process. The task manager in this is a great helper. However, you can resort to a simple reboot and log into the system through a secure mode. That is elementary achieved as a result of short-term pressing of the "F8" key. Using this version of the input, it is likely that the file can be eliminated without much difficulty, so to speak, the standard OS facilities. However, sometimes these tips are also incapacitated. But there is always a way out of the difficult situation! We read further.

Unlocker program

With this software you not only get a practical answer to the question of how to delete an open file, but you can solve a lot of other difficulties when it is not possible to get rid of the "fastidious guest" of your system by any of the methods known to you. It is worth noting that the program is free, easy to use and absolutely "weightless", that is, it takes only a few MB of disk space. But nevertheless, the performance and efficiency of its functionality will save your time and save your nerves. Integrating into the explorer, Unlocker will be available for any action script. By the way, this program will perfectly cope with the decision of your question "how to delete protected files". However, more about this in the next chapter.

The owner of the system: we claim our rights

It may happen that by downloading or "dropping" a file on the PC, in the future you will not be able to delete it. It's only because you will not have the rights to produce such an operation. Of course, not always programs effectively solve the complications that arise in one or another situation, nevertheless there is a non-failing method. So, how to delete a pdf-file or other format data that the system perceives as protected. Elementary: to become the owner of information and manually "rewrite" all rights to yourself.

• Right click on the selected file to call the submenu.
• Select "Properties".
• Then go to the "Security" tab.
• Next, "Advanced."
• Now the 3rd tab on the left, click on the "Owner" right, where you need to click on the "Edit" button.
• Now we point to our administrator's rights and become a full owner of the "pseudo-secure" file.

Practical user

Perhaps, for some users, this information will become not just a guide to solving an earlier unattainable task, but a kind of revelation of the opportunities that are opening up. As a rule, many standard Windows tools: media player, browser, various editors or other integrated applications - are rarely used. Many of us install more convenient and much more efficient software solutions on PCs. There is a natural desire to get rid of Microsoft's "imperfect" software. But not everyone knows how to delete the files "Windows", because the OS initially prevents the destruction of "their property." But this "short-sightedness" of Windows developers can be fixed. To do this, we resort to the already known method - we become owners of system files. However, we will somewhat extend the resolving power of our influence on the operation of the OS.

• Repeat all the actions of the previous paragraph.
• After the notification that you have become the owner of the file pops up, click on "Properties".
• Then: "Security."
• The next click on the "Edit" button will open a window in which you need to place markers opposite the corresponding items.
• Now nothing restricts you. The system file can be deleted.

Of course, do not get carried away, as you can "demolish" the critical components of your OS. Be prudent and extremely careful in your choice. By the way, the next chapter will help you in solving a rather common question "how to delete a video file that does not want to free up the occupied disk space, and everything else is not opened by any software tool."

Powerful Windows

The problem of unreadability of this or that data format can be solved without the sometimes difficult searches and installation of special software. In this case, you should pay attention to the standard function of the OS family Microsoft-HDD check for errors. Often, users have the question "how to delete a damaged file", the answer to which, among other things, is simple, but still needs a special explanation. The fact is that the system can not remove what it can not read, and it's a fact! You need to scan the disk (partition) in which there is an unreadable file, but you can do it the following way:

• "My computer".
• Click on the disk that contains the damaged file, right-click.
• Now "Properties".
• Then "Service".
• And in conclusion - "Check".

It is worth noting that in rare cases, the system refuses to perform this action through the above service. A variant of the console launch of the utility is possible:

• Start Menu.
• Execute - "cmd"
• Then, on the command line, write: chkdsk with: / f

Where (c:) is the disk partition, and (/ f) is the parameter to correct the error.

Attention: if you check the system partition of the disk, a message may appear that the scan will be performed the next time the OS boots. Nevertheless, you should agree with this proposal and enter the letter "Y", which will be a confirmation of your actions.

Another important point in the decision, when "wounded information" is not deleted. You can try changing the file name, that is, rename it. Also, it would not be superfluous to try to change the extension to the "forced uninstallation" object. For example: change avi to txt.

Warning: the system is in danger!

Now you know how to delete system files and that protection can be bypassed. Nevertheless, you should always remember that you can not foresee, with your own hand, cutting down Windows, and even more so to prevent erroneous changes in the operation of the OS. Possessing superficial knowledge and not understanding the severity of the consequences, thoughtlessly making corrections and destroying executive files, dll-libraries or disabling critical operating systems, the user jeopardizes the functionality and full functionality of the software part of the OS. Therefore, always remember the old good saying: seven times measure - one ...

Finally

Within the framework of this article, the main methods of deleting files were considered. Nevertheless, sometimes it is not necessary to resort to complex variants of the process of destruction of certain data ... In general, the Unlocker program copes with various "neponyatkami" competently enough. And yet, no one is immune from the virus's penetration into the Windows environment, and in fact "malicious code" can be the cause of the undelete file. However, this is the topic of another article. Let the insoluble problems recede from you!
