A brief introduction of File System in Windows
The way computers store files on disk has a close relation with File System which is
used to control how data is stored and retrieved. File System separates all data
into pieces and gives each piece a name so that the information can be easily
isolated and identified. The structure and logic rules used to manage the groups of
information and their names are called a file system.
There are several file systems frequently used in Windows OS including File
Allocation Table (FAT), Extended File Allocation Table (exFAT) and New Technology
File System (NTFS) etc. FAT32 in the first one and NTFS are the most two popular
file systems nowadays in Windows operating systems like Windows 7, Windows 10, and
Windows XP and so on. Therefore, when people talk about change file system without
formatting, they basically talk about converting NTFS to FAT32 or
in turn without losing data.
FAT32 is an old file system first introduced by Microsoft in 1996 which used as an
extension of FAT16. The standard maximum volume size for FAT32 is 2TB and the
maximum single file size is 4GB and compare to former version it has better
performance, more flexibility and robustness. However, NTFS, as its name implies, is
pretty new with advanced techniques in this field. Comparing to FAT32, NTFS is more
powerful in data security, data consistency, read & write and retrieval.
When do you want to change partition file system without formatting?
Although NTFS is more advanced than FAT32 as covered before, it cannot replace FAT32
totally, at least presently. FAT32, as traditional file system, is compatible with
many external medium such as XBOX, PS3, and Android and so on. So some users would
like to reformat to FAT32 from
NTFSsometimes for other purposes. Following real situation illustrates why
they want to convert file system.
