Let's see first how to put the password to a folder on PC. Below you will find explained how to do it on Windows (using a third-party application) and on macOS (using a system function useful for the purpose).
How to put the password to a folder on Windows
If you use a PC Windows and you are interested in password protecting a folder, I highly recommend you rely on VeraCrypt. It is a completely free and open source encryption software that has taken the baton of TrueCrypt, a very popular multi-platform program whose development ceased in 2014.
To download VeraCrypt on your PC, click here, in order to connect to its website and then press the link Download which is at the top and, on the page that opens, click on the link VeraCrypt Setup x.xx – Update-x.exe, placed in the section Windows. Wait a few moments for the program to download to your computer, then start the .exe file obtained and click the button Yes.
Accept, therefore, the conditions of use of the application by placing the check mark next to the item I accept the license terms and complete the setup by clicking in sequence on Next twice consecutively and then on the buttons install, OK, Finish e No.
Now that you have completed the installation of the program, to put the password to a folder (or, rather, to create an encrypted virtual volume), you must first start VeraCrypt by double clicking on its icon that has been added to the desktop and translate its interface in cittàn by going to the menu Settingsby clicking on the item Language, selecting thecityno in the window that opens and then clicking on the button OK.
Then click on the button Create a volume... to start the creation of your encrypted archive in which to insert the files to be protected, put the check mark next to the item Create a crypto file and click on NEXT to go to the next step. Then select the option Standard VeraCrypt volume, pig sul sul bottone NEXT and click on the button Select file... to select the folder in which to save your encrypted archive and assign it a name, then click on the button Save.
When done, click NEXT, choose the encryption algorithm to use for your volume (also leave the default setting on: BEA at the section Encoding algorithm e SHA – 512 at the section Confusion algorithm) and keep going. Then set a maximum space limit for the archive that will have to contain your files (in KB, MB o GB) and click on the button again NEXT.
Now you have to set the password to use to access your "folder": create one that is difficult to guess, perhaps consisting of more than 15 characters containing numbers and special characters, and keep it in a safe place ... if you forget it you will no longer be able to access to your precious data! Once you have entered and confirmed the chosen password, click on the button NEXT for the umpteenth time.
As a last step you have to choose which one file system use for the encrypted volume in which you are going to store your files: if you intend to protect videos, ISO images or very large archives, which weigh over 4GB, choose NTFS; otherwise leave the setting on FAT:. If you want to create a volume that can be used not only on Windows but possibly also on macOS, without having to face the limit of 4GB per file, opt for the file system exFAT.
Once you have selected the file system that best suits your needs, click on the button Format and, to complete the creation of your encrypted archive, first click on the button OK and then Logout.
At this point you can finally say you are satisfied: you have managed to complete the whole procedure to put the password to a folder and now you have at your disposal an encrypted archive in which you can store files of all kinds to protect them from eyes and "clicks" indiscreet. Compliments!
To access your "secret" volume, all you have to do is select one of the available drive letters (eg. J:), click on the button Select file... which is located at the bottom right and select the encrypted archive you created earlier.
Next, you will need to press the button Monta, type the password to access the volume by entering it in the field next to the item Password: and click on the button OK. If you entered the exact keyword, in the sections Computer resources, computer or What PC Windows (the item may vary depending on the version of the operating system in use). By doing so, the virtual drive icon created by VeraCrypt will appear and you will be able to manage the data inside your encrypted archive as if it were a USB key or any external hard drive.
When you have finished using your private "folder", go back to the VeraCrypt main screen, select the drive letter you "mounted" previously and click on the button Disassemble to make the volume disappear from the PC.
How to put the password to a folder on Mac
VeraCrypt, the program I told you about in the previous lines is also available for MacOS, consequently you could use it in the same way as already seen on Windows PC to put the password to a folder on Mac (taking into account that the version for macOS is in English and needs an add-on, called FUSE, to work). More info here.
In reality, though, you might as well do without and use Disk utility, The included "standard" in all versions of MacOS that allows you to manage disks and their partitions very simply and easily. The trick - if we want to call it - is to create an image encrypted disk and store inside it all the files you want to protect. You understood perfectly well: on Mac it is possible put the password to a folder without programs third-party.
If this solution interests you, proceed as follows. To begin with, start Disk Utility by clicking on its icon attached to the folder Other of Launchpad. Alternatively, you can open Disk Utility by going to the folder Applications and then double clicking on the tool icon or searching for the application using Spotlight.
Now that you see the Disk Utility window on your desktop, click on the entry Fillet located in the upper left part of the menu bar and then select the item New image and then that Blank image... and set the drop-down menus in the window that opens as follows.
- At the entry dimensions: indicates the maximum size that the archive must reach (choose it according to your needs).

- At the entry Coding: select 128-bit AES encryption.
Now, type the Password to be used to encrypt the disk image in the fields Password e Verifica and click on the button Choose. Then enter the name you want to give your volume in the text field Save col nome: e Name:, choose the location on your Mac to save everything via the menu Located in: and click on the button Save. Finally click on the button end.
Once you have completed all the procedure to put the password to a folder, or rather to create an encrypted disk image, to view its contents and modify it (i.e. add other data inside it), all you have to do is open it with a simple double click, type the password you previously set in the appropriate field next to the item Password: attached to the window that is shown to you on the desk and press on OK.
To "unmount" the volume, click on the symbol Eject located next to its name in the Finder sidebar. Did you see how simple it was to encrypt a folder with Disk Utility?
How to put the password to a folder on smartphones and tablets
I conclude this guide by explaining to you how to put the password to a folder on smartphones and tablets. Below you will find explained how to succeed on the main mobile platforms: Android and iOS / iPadOS.
You have a device Android? Well, in this case, to protect a folder with a password, all you have to do is install a file manager that has the folder encryption functionality (if you haven't already), call up the feature in question and create a password to protection of documents contained in the folder of your interest.
One of the best file managers you can use for this purpose is Solid Explorer File Manager, which costs 2,99 euros, but can still be tested for free for 14 days. Let's see how it works.
After installing Solid Explorer on your device, tap the button Following, to scroll through the information sheets that illustrate the features of the app (or, if you prefer, salta the initial tutorial, by tapping the appropriate button), put the check mark on the box I accept the license agreement and press on the item Done, I will continue.

iOS / iPadOS
You would like to know how to password protect a folder on iOS / iPadOS? Well, in this case, although it is not possible to obtain this result exactly - the Files app that allows you to manage files and folders on Apple portable devices does not have this feature - you have various alternative solutions to turn to: use aapp to create password protected vaults, create encrypted notes in theNotes app and block access to apps using the function Usage time. Let me describe all these solutions to you.
To create password protected vaults, I recommend using Private Photo Vault, an app through which it is possible to create “software safes” in which to hide private photos and videos. After installing and starting the app on your device, tap the button Start e poi premi sul pulsating Set passcode: create, therefore, a secure password with which to protect your private photos, typing it twice consecutively.
Then press on the item Creation, provide a backup email address using the text field that appeared on the screen and then presses the button Concluded. Now, tap the button NEXT twice in a row, presses on the buttons I agree e Accept everything and continue and start using the app.
To create a new private album, press the button capacitor positive (+) lead located at the top right (in the screen Album), give a album name and possibly set a Password with which to protect access. Next, tap the button Crea placed at the top right and that's it. To insert content into the album in question, tap his name, type the Password possibly set to protect the latter and answer OK notice appeared on the screen.
Next, tap the button capacitor positive (+) lead located at the bottom right, select the way to import the photos of your interest (Photo archive o Camera) and, after selecting them, wait for them to be loaded. To access any content saved in the app, you will then be asked to enter the passcode set during its configuration (the request will be made even if the app is not actually closed). Interesting, right?
Do you want to password protect notes? It is also possible to do this: just take advantage of the special function integrated in theNotes app. After starting the latter, locate the note of your interest, keep your finger pressed for a few seconds on his title (or make a decisive tap on it, if your device is equipped with 3D Touch) and select the item Protect note in the opened menu. You just have to type the Password with which to protect the content of the note, in the appropriate text field, and finally tap on the item OK.
Do you want to prevent access to the apps installed on your device? Thanks to the function Usage time it is a doable thing. To use it, go to Settings> Usage time> Use the "Usage time" code and sets a four-digit numeric code (twice in a row).
Successively, recati nella sezione App limitations, tap on the item Aggiungi LIMITATION OF USE, type the code set up earlier and look for the name of the apps you want to block (eg. Fillet), and then select them. Next, tap on the item NEXT, set the timer for the app usage limit to 0 pray and 1 min (which is the minimum allowed), confirm the operation by pressing on the item Add And that's it. To block access to the selected apps, then launch them and wait for the minute to pass.
If you have second thoughts, go back to Settings> Screen Time> App Restrictions> [Category], type il code currently set, tap on the item Eliminate limitation and confirm your intentions by tapping the item again Eliminate limitation in the opened menu.
