Change File System between NTFS and FAT32 without Formatting
A brief introduction of file system in Windows
The way that computers store files on disk has a close relationship with the 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.
Nowadays, FAT32 and NTFS are the most two popular file systems in Windows operating systems like Windows 7, Windows 10, Windows 11, Windows XP, and so on. Therefore, when people talk about changing file system without formatting, they basically talk about converting NTFS to FAT32 or in turn without losing data.
◤ FAT32 (File Allocation Table 32)
FAT32 is an old file system first introduced by Microsoft and used as an extension of FAT16. The standard maximum volume size for FAT32 is 2TB and the maximum single file size is 4GB compare to the former version it has better performance, more flexibility, and robustness.
◤ NTFS (New Technology File System)
NTFS, as its name implies, is pretty new with advanced techniques in this field. Compared 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 a traditional file system, is compatible with many external mediums such as XBOX, PS3, Android, and so on. So some users would like to reformat to FAT32 from NTFSsometimes for other purposes. The following real situation illustrates why they want to convert the file system.
"All partitions' file system is NTFS now in my Windows 7. I want to format the D drive from NTFS to FAT32 because the program I'll use does not support backup unless it is FAT32. What can I do to change the drive file system without formatting and losing data? "
What's more, FAT32 has a deadly limitation that a single file should not be larger than 4GB. Thus, converting file system is a must-do event when you have large files say DVD ISO files on FAT32 partition to read, especially on a USB flash drive.
