Unfortunately, there is no built-in feature available for Windows users for that specific task. But you can use third party tools like Lacie Free Encrypted Tool to Encrypt your Folder.
Here Are The Simple Steps to Encrypt Folder In Flash Drive:
You need to download ZIP Files From Lacie website. Download and extract the files.
Copy All Extracted Folders and paste into your USB Flash Drive.
Remember “this folder should be copied and pasted into root, it shouldn’t be inside any subfolder, otherwise it won’t work”
Paste all the Extracted Folder inside your USB Flash Drive.
Go to the extracted Folder and find the private-public.exe file and run it.
This is where you can give a size to your folder, in my case i’m just using 500mb for demonstration. After giving the size of your folder simply click on “Next”
Now Create a password for that folder: choose the password and click next.
Hit Next and process will start in few seconds, it also depends on your data and PC performance, usually it takes 1 minute per 1 GB transfer.
When it’s done, it will take you to disk mounting process. Here, you just need to put your created password in the fields.
It’s almost completed, if you go to “my computer” you can see there are some other drive pop-ups! which you have created. Put all the sensitive data in it and it will automatically save into encrypted folder inside Flash Drive.
Now all of your data in that encrypted drive is protected through encryption and once you disconnect the USB Flash drive, the encrypted drive will go away from sidebar or in “My Computer”.
When you reconnect your Flash Drive, it will not going show you the encrypted folder which you have created, because it’s hidden. In order to retrieve that you need to go to your USB storage and again run the private-public.exe, and this time it will just ask for a password.

Are There Any Risks Of Encrypting Flash Drive?
When we think about encryption, it always seems beneficial which is mostly true. However, in encrypting a flash drive, there are some issues to which a user is still prone.
The password could be the greatest issue as the whole encryption process depends on keeping a strong password. If your password is easy to guess or doesn’t contain strong characters then there are chances that it could be revealed.
Most people write down the password to remember it which produces the chances of losing it. Also, if the encrypted flash drive is entered into a compromised device with key logging software then you may lose the password while entering it.
However, the most probable risk is the loss of password if you forget it and there is no chance to decrypt USB data without password. But, there are the ways to recover password such as BitLocker’s recovery key or a clue or to store it securely.
