Want to hide files in a secret locked folder in Windows 10 or 11? Encrypting a folder allows you to lock the folder to anyone who doesn't have an encryption key. We'll show you how to encrypt files in Windows 10 or 11 Pro or Enterprise editions in File Manager, and how to use AxCrypt to lock folders if you're using Home edition.

Method 1

Method 1 of 3:

Locking Folders in Windows Pro & Enterprise Editions

1
Press ⊞ Win+E to open File Explorer
. The File Explorer icon is a folder with a blue clip. You can click the File Explorer icon in the Windows Start menu or press the Windows Key + E to open File Explorer.
2
Navigate to the folder you want to lock. Use File Explorer to navigate to where the folder you want to encrypt is stored on your computer.

3
Right-click the folder and click Properties. Right-clicking a folder displays a context menu. Click Properties at the bottom of that context menu.
4
Click Advanced. It's the button at the bottom of the Properties menu under the "General" tab. This displays the Advanced Attributes menu.
5
Click the checkbox next to "Encrypt contents to secure data" and click Ok. This selects the option to encrypt the folder.
- This option is not available in Windows 10 & 11 Home Edition.
6
Click Apply. It's at the bottom of the Properties menu. This applies the changes you have made. A pop-up menu will appear asking if you want to encrypt just the folder or all the subfolders and contents within the folder.
7
Select "Apply changes to this folder, subfolders and files" and click Ok. It's the second radio option in the pop-up menu. This applies encryption to all the folders and all the contents within.
- Alternatively, you can click "Apply changes to this folder only" to apply the encryption to the folder only, and not to any of the subfolders or contents within.
8
Click Back up your file encryption key. When you apply the encryption, you will receive a notification in the lower-right corner asking you to back up your file encryption key. Click the notification to display the options for backing up your encryption key.
9
Click Back up now (recommended). It's the first option that appears in the pop-up when you click the notification.
10
Click Next. This page explains that the certificate export wizard will help you export the certificate for the encryption key. Click Next in the lower-right corner to continue.
11
Select the format you want to use and click Next. The default file format is "Personal Information Exchange (.pfx)," but you can select one of the other options if you would rather use them instead.
- If you are not sure which option to select, go with the default Personal Information Exchange. Click Next to continue.
12
Click the checkbox next to "Password," create a password and click Next. To create a password, click the checkbox next to "Password" and then enter a password on the line below it. Enter the exact same password again on the line below "Confirm password" and then click Next in the lower-right corner.
13
Insert a USB thumb drive. Since the certificate contains the key needed to open your encrypted folder, the safest place to save this file is on an external hard drive, such as a USB thumb drive. Insert a USB thumb drive into any available USB port on your computer.
14
Click Browse and select a location of your thumb drive. Click the button that says "Browse" next to the bar that says "Filename." Then select your USB drive.
15
Enter a filename and click Save. Enter the filename for the encryption key certificate in the line that says "File name." You can enter any filename you want, but you should use a filename that you recognize as the encryption key for your folder. Click Save when you are done.
- Be sure to save the USB drive in a safe location. You will need it if you are not able to access the encrypted folder for any reason.
16
Click Next and then click Finish. After saving the encryption key certificate, click Next to continue to the last page in the Export wizard. The last page shows a recap of all the steps you have taken. Click Finish to close the export wizard. The folder is now locked to all other users except for you.
- You can access your encrypted folders as long as you are signed into Windows under your user account. No other Windows user (including the admin) will be able to access the folder.
- If your user password is changed by an administrator, or you move the encrypted folder to another computer, you will not be able to access the folder. You will need to import the encryption key certificate to regain access to the folder.^{[1]

Question

Have locked folders on a USB but after they are locked can still search with a file extension (eg. docx) and all files with that extension will show up! Not much point locking them.

What's the logic to lock the folders? To not allow access to files or to completely hide the folder from search parameters? You can right-click, then properties, then on the bottom you can choose "hide"; however, you're probably best off by restricting the permissions of the folders to access only by you through the System Permissions of the file or folder.
