Programs to delete unnecessary files
Let's start this excursus among the resources to delete files from the computer by software for the removal of unnecessary elements. Below, therefore, you will find those that in my humble opinion are the best programs to delete unnecessary files on Windows and macOS: try them and you won't regret it.
Disk Cleanup (Windows)
To get rid of unnecessary files on your PC Windows, you can first resort to the use of a tool included "steard" in all versions of the operating system from Microsoft: Cleaning disk. The latter allows you to delete all temporary files and no longer useful data that are present on the disk.
To take advantage of it, log in to the Start menu, digita disk cleaning utility in the search field and click on the corresponding reont. In the window that opens on the desktop, then select theunit in relation to which it is your intention to go to act from the appropriate drop-down menu (eg. C:) and click on the button OK.
Now, put a check mark next to the items related to the items you want to remove (eg. Temporary Internet files, Trash can etc.) and presses the button OK to start cleaning.
If you also want to get rid of system files that are no longer useful (e.g. residual files from Windows updates), please note that you can do this by clicking on the button System file cleanup placed at the bottom. But if you don't know where to put your hes, I advise you to let it go.
Default Disk Cleanup Tool (macOS)
Let's now turn to the side MacOS. Even then, to get rid of unnecessary files, you can take advantage of it in the first place default disk cleanup tool which Apple has chosen to include on all Macs starting with MacOS Sierra.
To use it, click the button in the shape of apple located in the upper left part of the menu bar e select the item About this Mac from the menu that opens. Then click on the tab archive in the window that appears on the desk and presses the button Manage that you find at thecomputer hard disk icon.
In the new window that will open at this point, choose whether or not to carry out the operations attached to the card Advice (Eg. store files on iCloud or optimize the iTunes library), by pressing the relative buttons. Instead, to perform more targeted cleaning operations, click on the tabs on the side (eg. Trash can, Documents, Mail etc.) and take advantage of the various functions agolable in the right part of the window. That's all!
If the resources already included in Windows and macOS don't satisfy you, you can turn to CCleaner to get rid of unnecessary files on your computer: it is one of the most famous software belonging to the category, useful for deleting junk files from the hard disk, as well as for solving errors in the Windows registry and carrying out various other maintenance operations. It can be used on both Windows and macOS and the basic version is free, while the Pro variants are paid (have a basic cost of 19,95 euros).
To download it on Windows, connected to the program's website and clicks on the link CCleaner.com present in the column Free. A download complete, apri il file .exe obtained e, in the window you see appear on the desktop, click on the button Yes.
Se, invece, stai using MacOS, april il package .dmg ottenuto, trascina l 'software icon in the folder Applications on your Mac, right-click on it and select the item apri from the menu that appears, in order to circumvent the limitations imposed by Apple on applications from non-certified developers (an operation that must be performed only at the first start).
Now that, regardless of the operating system used, you see the CCleaner window on the screen, to locate and delete unnecessary files click on the tab Cleaning / Cleaner, press the pulsating Start Cleaning / Run Cleaner and confirm the execution of the operation by clicking on the button OK. Eventually, you can also just scan the disk and know how much space you could free up with CCleaner without actually deleting the files. To do this, click on the button Analyze / Analyze.
Before starting the cleaning operation you can also choose which files to delete and which not, by selecting or deselecting the items in the left sidebar, in the tabs Windows / Mac OS X and Applications / Applications. If you are not sure what to do, however, I suggest you leave the default settings active, otherwise you risk doing serious damage!

Programs to permanently delete files
Let's move on to the programs to permanently delete files, that is, those which, while resorting to the use of tools for recovering deleted data (such as those I pointed out to you in my guide on the subject), make it practically impossible to carry out this operation. Find them indicated below.
Moo0 FileShredder (Windows)
Moo0 FileShredder is one of the best programs for safe file deletion for operating systems Windows. It is characterized by a very easy to use user interface, through which it becomes a breeze to delete any type of file permanently. There are four levels of cancellation to choose from and it's totally free.
To download it to your PC, connect to the program download page on the website of MajorGeeks and click on one of the connections that you find under the heading Download Locations top right.
When the download is complete, open the file .exe ottenuto and click on your button Si in the window that appears on the desktop. At this point, remove the check from the box next to the item Additional Free Tools (to avoid installing extra programs), click on the button NEXT, check the box I accept the Conditions and click on the button again NEXT (three times) and then on the buttons Install and Close.
At this point, drag the file you want to permanently delete on the Moo0 FileShredder window that in the meantime has appeared on the desktop, then click on the button Si and it's done. Easier than that?
Note that by default the method used for deleting files is that simple (it is the fastest but least accurate one). If you want to change it, before starting the deletion procedure, choose the option you prefer from the drop-down menu Method which is located at the bottom. The options agolable, apart from the simple method, are as follows: Vaporization (it is the most effective but slowest), Thorough and Incinerator (they are somewhere in between, the first is slightly less secure than the second but a little faster).
Permanent Eraser (macOS)
Se, invece, stai using MacOS, I recommend that you consider using Permanent Eraser to permanently delete the files on your computer: it is a small free utility that works by deleting files in an irrecoverable way, overwriting the data 35 times, mixing the names of the original elements and truncating their size. It is very easy to use and can be used both from the Recycle Bin and directly on individual files as well as with CDs and DVDs.
To download it on your Mac, connect to the appropriate section of the Mac App Store online, press the pulsating See in the Mac App Store e click your bottone Ottieni / Installa in the window of Mac App Store which opened on the desk. If necessary, authorize the download by typing the Password of your Apple account or via touch ID (if you have a Mac equipped with this component).
Next, move the files you want to permanently delete to the Trash can, click onicona dell'applicazione which was added to the Launchpad (or from the folder Applications, through Spotlight or, again, by Crab) and press the pulsating OK in the window that appears. On the desktop you will then see a new window appear with a bar indicating the progress of the operation.
As regards, however, the deletion of files in locations other than the Recycle Bin or to intervene on CDs and DVDs, all you have to do is, very simply, drag the icon of the reference element into that of Permanent Eraser.
