Introduction to NTFS's advanced features

NTFS is an advanced file system with several improvements to FAT and HPFS (High Performance File System), providing long file names, data protection and recovery, and through directory and file permissions. Security. Files on NTFS partitions are not directly accessible from DOS or other operating systems. But in Windows 2000 and Windows XP, NTFS can also provide advanced features such as file and folder permissions, encryption, disk quotas and compression. Today, I will give you a detailed introduction to these advanced features.

File or Folder

Step 1: Open Windows Explorer.

Step 2: Right-click on the file or folder you want to encrypt and click “Properties”.

Step 3: On the "General" tab, click “Advanced”. Check the “Encrypt content to protect data” checkbox

Note the following five points during the encryption process:

1. To open “Windows Explorer”, please Click “Start →Programs →Accessories", and then click "Windows Explorer”.

2. Only files and folders on the NTFS partition volume can be encrypted. The files and folders on the FAT partition volume are invalid.

3. The compressed file or folder can also be encrypted. If you want to encrypt a compressed file or folder, the file or folder will be uncompressed.

4. Files marked as “system” cannot be encrypted, and files located in the systemroot directory structure cannot be encrypted.

5. When encrypting a folder, the system will ask if you want to encrypt its subfolders at the same time. If you select Yes, its subfolders will also be encrypted, and all subsequent files and subfolders added to the folder will be automatically encrypted when added.

Second, decrypt the file or folder

Step 1: Open Windows Explorer.

Step 2: Right-click on the encrypted file or folder and click on “Properties”.

Step 3: On the "General" tab, click “Advanced”.

Step 4: Clear the “Encrypt content to protect data” checkbox.

Similarly, we should pay attention to the following issues during the process of decryption: 1. To open "Windows Explorer", click "Start → Program & Rarr; Attachments" and click “Windows Explorer”.

2. When decrypting a folder, the system will ask if you want to decrypt all files and subfolders in the folder at the same time. If you choose to decrypt only the folder, the encrypted files and subfolders in the folder you want to decrypt remain encrypted. However, new files and folders created within the decrypted folder will not be automatically encrypted.

The above is the method of using file encryption and decryption! In the process of use, we may encounter the following problems, here are the following instructions: 1. Advanced button can not be used Reason: Encrypted File System (EFS) Only files and folders on NTFS file system volumes can be processed. If the file or folder you are trying to encrypt is on a FAT or FAT32 volume, the advanced button does not appear in the properties of the file or folder. Previous12Next page Total 2 pages
