Windows Recycle Bin

Eraser for Windows

This is one of the most popular free utilities that allow you to delete files without recovery. Unlike the “permanent” removal option available in the Windows Recycle Bin, the application erases them permanently. Eraser works by writing random data over the file until it can no longer be restored.

First of all, you need to find the object that you want to delete, and right-click on it. A pop-up menu will appear, similar to the one before the installation of the utility. But now it contains the Eraser line, located above the "Open with" item.

Next, open the submenu and select the Erase option. To do this, hover over Eraser in the context menu and hold it there until another menu appears. In it, select the Erase item to delete files without the possibility of recovery. The program will immediately do what is required, after which a pop-up window will appear informing about the completion of the task.

Instead of the Erase command, the user has the option “Erase on reboot”. In this case, the file will not be deleted immediately, but the next time the computer starts.

SDelete for Windows

SDelete is an unrecoverable file removal program created by Microsoft. It allows you to do this from the command line of the Windows operating system. This utility, like Eraser, cyclically writes zeros and ones on top of files on disk until the original data turns into a set of random values. She does not delete their names, but completely and permanently erases the contents.

The program is launched from the command line. In the "Start" menu, select "Run", enter the cmd command in the "Open" text box and press the "OK" button or the enter key on the keyboard.

Then you need to go to the folder with the SDelete utility. To do this, use the command to change the current CD directory.

For example, if the program is located in the C: \ tools directory, then at the command prompt you should enter CD C: \ tools. After that, you need to press the enter button, and the specified folder will become current.

You can sdelete [] < > what exactly needs to be deleted by typing sdelete [] < > at the command line. The following values ​​can be used as parameters:

  • -p [N] - allows you to overwrite the file N times. For example, if you need to do this 30 times, enter -p 30;
  • -a - removes the read-only attribute;
  • -s - cleans free space;
  • -q - suppresses the output of information about errors in the execution of a command;
  • -s or –r - sets recursive access to subdirectories;
  • -z - instructs the command to fill the file with zeros after it has been overwritten with zeros and ones. It is used to optimize virtual disks.
SDelete program

The file name should include the path to it. For example, to erase the text file passwords.txt, which is located in the folder C: \ Public Documents \, you would enter C: \ Public Documents \ passwords.txt and press the enter key. After that, the utility will start and erase the specified object.

Upon completion, a confirmation line appears on the command line that the data has been permanently deleted. At this point, the cmd window can be closed. Mission accomplished.

Trash on Mac OS

To delete a directory or file, go to the object you want to get rid of, left-click on its shortcut and press the Delete key or drag it to the "Recycle Bin" icon located on the taskbar.

By clicking on the “Recycle Bin” label and holding the button down, you can open the options menu. Two options are usually available: “Open” and “Empty Trash.”

When you select the last value, links or paths to objects in the "Trash" are deleted. This allows you to get more free space on your hard drive, but the data does not completely disappear. They can be restored later if only the standard cleaning method was used.

When you hold down the Command key while the Recycle Bin menu is open, the name of the option to clear it should change. Now this is the inscription “Irrevocably empty the Recycle Bin”.

Selecting this option allows you to delete deleted files without the possibility of recovery. In this case, the entire contents of the Recycle Bin on the computer’s hard drive will be erased. But in this way, you cannot delete 1-2 specific files and leave the rest untouched.

The function is available only on MacOS operating systems starting with version 10.3.

Some users may experience problems during this procedure, and a message will appear on the screen stating that the action cannot be completed because a certain object has been blocked. In this case, you can try to press Option and select the "Trash" item from the Finder menu. If this does not help, you should look for another reason.

Owners of MacOS X 10.0–10.0.4 can try right-clicking on an object and, having activated the “Information” option, make sure that there is no flag opposite the “Block” option. If this does not help, then you should look for the answer on the Apple tech support site.

You can also check if the user has permission to modify the file. If not, then most likely a warning will be displayed that the owner does not have enough permissions and privileges. Starting with MacOS X 10.2, users can run the command “Restore access rights to disks” in the menu “Programs - Utilities - Disk Utilities”. If this does not help or a different version of the operating system is installed, then you should read the explanations on the Apple support site.
