How to Resize NTFS Partition without Losing Data

Overview of NTFS

NTFS (Windows NT File System) is the standard file system of Windows NT, including its later versions Windows 2000, Windows XP, Windows Server 2003, Windows Server 2008, Windows Vista, Windows 7 and Windows 8/10.

NTFS is a high-performance and self-healing file system proprietary to Windows XP, Vista, 2003, 2000, NT & Windows 7 and Windows 8, which supports file-level security, compression, and auditing. It's also compatible with storage devices with large volumes and huge storage devices such as RAID. The most important new feature of NTFS is the ability to encrypt files and folders to protect your sensitive data. To avoid crippling Windows NT, Microsoft created a new file system that was not based on FAT - New Technology File System or NTFS.

Advantages of NTFS

NTFS was designed to meet some specific goals. The following are reasons why you should choose NTFS to be your partition file system:

1. Reliability: NTFS can help to avoid data loss, and improve fault tolerance during the process of recovery.

2. Security and Access Control: NTFS has a built-in facility for controlling access to folders or files on a hard disk. So it can implement applications and networks that require security and the ability to manage who can read or write various data.

3. Storage Efficiency: When NTFS was developed, most PCs used FAT16, which resulted in wasting some disk space. NTFS avoids this problem by using a different method of allocating space to files than FAT does.

4. Breaking Size Barriers: NTFS supports huge partition sizes, in anticipation of growing hard disk capacities, as well as the use of RAID arrays.

5. Long File Names: NTFS allows file names to be up to 255 characters, instead of the 8+3 character limitation of conventional FAT.

Need to resize NTFS partition

Due to these points, NTFS is not only the most commonly used file system at present, but also tend to replace FAT file system some day. To maximize the performance of NTFS partition, we need to organize our NTFS partition regularly. When NTFS partition runs out of space, the most helpful operation is to extend NTFS partition.

What do you concern about most when you resize NTFS partition? Easy operation? Data security? I think the answer is "both". To resize NTFS partition safely, this article will provide a free partition manager to resize NTFS partition without any data loss.
