In Windows, you can easily encrypt a drive or operating system drive using BitLocker. But when it comes to single file or folder, you can’t use BitLocker to encrypt. For this case, Windows has yet another useful option. You can use the Encrypting File System (EFS) feature which is used for encryption in NTFS file system. Once the file is encrypted, only the person having access to it can decrypt it using password. This will make file/folder secure as the unauthorized person can’t access/modify it. Always remember, when you encrypt file/folders you must backup its recovery key, else may lose access to the content.
So if you’re looking forward to encrypt a file/folder, try the below mentioned simple steps.
