Sometimes it becomes necessary to completely delete files, i.e. unrecoverable deletion. Let's say you decide to sell hDD or a flash drive. In this situation, I would not want the next owner to be able to restore confidential information that was stored on the device earlier. After completing the usual formatting, the data can still be restored, we talked about this in the video tutorial “R-Studio - recovering deleted files”.
It is advisable to check the programs and drivers before installing them in order to avoid abnormal operation of the system. Effectively recovers in the event of a system failure. Deleted items go to the trash where they remain until they are automatically deleted after about 90 days.

There are programs that permanently delete the files that we specify. But what about data that has already been deleted? They can not be specified in the program! For this reason, we consider cleaning up free space. That is, first you delete unnecessary files, run the program and it fills the free space with zeros from which you can restore data.

But the file or folder is not lost. If you know the version in which the file or folder was deleted, open the repository browser and switch to this revision.
Moving files and folders
Enter a new name for the object and everything will be ready. If you want to move files to your working copy, possibly to another subfolder, use drag and drop by right-clicking.This program called CCleaner. It has gained fame as a program that cleans the system and disks of various debris, but it also has a function to clean free space that interests us. The advantage of CCleaner is that in free version There is also this feature, and analogues are paid.
To get started, download the program from the official site www.piriform.com \ Ccleaner \ DownloadfromPC \ Free \ Download.
That is, they will have both old and new copies. Before changing any files in this folder, you must rename the folder, otherwise your working copy can be really dirty. To move files, select “Context Menu” → “Cut” instead of “Context Menu” → “Copy”.
Manage file name conflicts
You can also use the repository browser to move items. This action will remove the external item from the parent repository, which can lead to a violation of many other people. Sometimes this happens when two people send changes to the repository, from separate working copies, files that have the same name, but with a different case.
We launch Ccleaner \\ Service \\ Erase Discs \\ Erase:
- The entire disk (all data will be lost) - in this case, all data from the media will be deleted and erased, i.e. analogue of formatting, only without the possibility of data recovery. This method can be applied in a situation if you decide to sell a hard drive or flash drive;
Avoid having two files with the same name
In this case, you must decide which of the two you want to keep and remove from the deposit.
Restore file rename
Delete unversioned files. But what if you want to erase all ignored objects to produce a clean generation? A dialog box opens with a list of all version files anywhere in your working copy, and then you can select or deselect the items you want to delete. When these items are deleted, the recycle bin is used, so if you make a mistake and delete the file that was supposed to be the version, you can still restore it.- Only free space - only free space is filled with zeros, without affecting the current data. This method can be applied when you sell a computer or laptop. That is, first we delete all confidential information, and then we clean the free space so that the data stored earlier could not be restored.
Method 1
Or your file may be damaged and you cannot open it. Step 3: Click “Open and Restore”. Step 4: Click “Yes” to confirm. it free program, which recovers lost and deleted data and performs only recovery functions. It allows you to undo deletion, copy files and create image files with hard drives. However it is software can only restore files whose data has not been overwritten.
Step 3: Take the file and click “Cancel Deletion”. You can select the location of the folder, scan the computer and conduct a thorough scan to find deleted files. It can quickly find all types of lost, deleted, damaged or formatted documents on your computer’s disk, as on external hard drives.
The repair method is very simple, but its effectiveness is not guaranteed.There are also several cleaning methods, they differ in the number of passes, i.e. number of rewrite cycles. Optimal will be 7, but if you expect a visit from special services, you can put 35 passes.
This process is quite long and depends on the volume. free space on a disk or drive, as well as the number of passes. Therefore, I will not now test the effectiveness of this cleaning, but I can say that after completing the work I checked in R-Studio and really the program could not find anything.
Quarantined file recovery
If you find that this file is necessary for the program or computer to work correctly, you can restore it to its original location.
Additional information and tips.
- Recover: sends the infected file to its original location.
- Recover as: sends the infected file to the selected folder.
Delete files permanently
If some files were not restored correctly, they remain highlighted in the list. If the source file was an attachment email, its original location is a temporary folder that is hard to find on your hard drive. Registry keys can only be restored to their original location.
You can delete files by dragging them to the trash can icon.
- To do this, select them in the list and click the corresponding button.
- For this reason, only the Restore As function is available for attachments.
- Delete: permanently deletes individual files.
- Empty quarantine: permanently deletes all quarantined files.
Sometimes it is vital to get rid of the data so that it is. Simply deleting to the trash will not be enough - such data is easily restored. If you thought that formatting made data recovery impossible, then you were mistaken - this is quite feasible.
However, you still have to spend it, and you can recover it later. Each of us sometimes deletes some files. Most users use a basket for this purpose, which stores data for later simple recovery. If you are sure that you do not need data, you simply blink.
It deletes files directly and does not save them in the recycle bin. If you want to delete large quantity smaller files, this operation can be much faster. However, you delete the file first or second, it is usually physically located on the disk somewhere. The system discards only the path that leads to it. Therefore, if you want to delete an important file that no one else should see, it’s good to overwrite it disk space with completely different data.
Moreover, even low-level formatting does not guarantee complete irretrievable data destruction. Of course, there is always the option of severe damage with a hammer, but far from always you want to lose the entire device, and no one can guarantee the accuracy of the blow - what if the disk can be repaired? :-) In general, as you probably already understood, this article is dedicated to permanent removal data by software methods.
This is not separate software, but simply a “gadget”. It is up to you to organize your instances. After adding to the Gallery with gadgets, you can place as much as you need for this gadget on your desktop. After placement, use the small arrows to the left and right of the banner to switch to individual basket types. Green means a normal recycle bin, and moved files remain empty. Red trash will immediately delete the file without saving it. And black will also overwrite it with other data.
The big advantage is now the ability to add multiple instances, each instance can represent one type. If you want to win even more with the gadget, you can see its settings. On the first tab of parameters, you can change the colors of each type of basket, stack size and display of control buttons. In the second tab, you can click on the basket and confirm that the files are moved to each type of basket.
A little useful theory
Any articles on the principles of recording and storing information on a hard drive on the network are enough and I will not retell them - if interested, then open, for example, Wikipedia. The only thing I mention is that remote file from hard drive it doesn’t really disappear anywhere and is easily restored exactly until any other information is written “on top of it”. Those. It’s not enough to delete the file and empty the trash, - it is necessary that something else is written to the same block on the hard disk. But, as far as I know, even two or three rewriting cycles is not enough and information can be extracted. And if serious professionals took up the matter, then, according to rumors and unverified data, the information is recoverable even from a physically badly damaged carrier, which, even for me personally, does not fit my head. However, this is not about that. So what to do with all these rewrites? After each deletion of information, to sit and copy some gigabyte archive back and forth in the hope that it will overwrite the necessary areas? You can be tortured :-) And here comes to the rescue ...
We use the CCleaner program for these purposes.
Yes, yes, this one about which I repeatedly wrote in my articles. This time comes to our aid again.
The fact is that in this wonderful program there is such a function as " Empty space". It doesn’t mean cleaning up the garbage in order to free up free space, but rather cleaning up the free space itself, that is, rewriting the very“ empty ”areas where the information you deleted was once stored. The goals are just those that I described above - make information unrecoverable by overwriting the "empty" areas of the hard drive ... with 0s.
How to actually turn it on? Yes, it’s very simple:
And that’s all. For the future, if you plan to keep information that should not fall into anyone’s claws, I highly recommend creating a separate logical drive and keep only these files on it, so that if you need to delete them, you can format the disk and start overwriting through from above, and not tick off almost all disks (if the information was on different disks) and not wait until all the free space is overwritten.
Afterword
Something like this.
If that - I did not advise you this, and you do not know me: -D
Just kidding :)
