Encrypting a file or folder is the preferred security method, since only you will have access to the data. The encryption method remains the same as in previous versions of Windows, but if you did not have to encrypt the data earlier, you will be able to learn how to do it.
Method 1: use a data encryption system.
Using the built-in encryption tool EFS (encrypted file system) is probably the fastest way to encrypt your data in both Windows 10 and other versions of Windows starting with XP.
This simple encryption tool will protect your files in a couple of minutes. It is important to remember that as a result, access to information that has been encrypted will only be possible from your account. You will not be able to access the file from any other account, even with administrator rights. In order not to lose access to the file or folder, be sure to write down the password.
So let's get started:
1. Click RMB on the folder that you want to encrypt, and select " Properties ".
2. In the " Attributes " section of the " General " tab, click " Other ".
3. Check the box “ Encrypt contents to protect data ”, click “ OK ”.
Then “ Apply ” and in the new window select “ To this folder and to all subfolders and files ”.
(if you do not want to leave the files inside the folder unencrypted - select the item " Apply changes only to this folder ")
Method 2: Encryption with Microsoft Office.
Office file encryption is very popular. Each Microsoft Office application has its own encryption system.
Follow these steps:
1. Open the document you want to encrypt.
2. Go to the file tab and click on the item starting with “ Protection ” (each application has its own name).
3. Select Encrypt with Password .
4. Enter the password twice and click OK .
Now the document can be opened only after entering the password.
Method 3: use a special encryption tool.
If you do not have enough features in the EFS encryption system - select third-party software that meets your needs. There are both paid and free versions of encryption tools. Paid software is supported by developers and has wide functionality, while free software will save money.
Many programs have a test period during which you can use the tool to protect your files and explore all the encryption options.
