FAT32 FORMAT which commonly used in xp but it has some restriction like single file size and security issue. So there is a way to change it without data loss or format.
Why we need It
Choosing Between NTFS, FAT, and FAT32
You can choose between three file systems for disk partitions on a computer running Windows XP: NTFS, FAT, and FAT32. NTFS is the recommended file system because it’s is more powerful than FAT or FAT32, and includes features required for hosting Active Directory as well as other important security features. You can use features such as Active Directory and domain–based security only by choosing NTFS as your file system.
How to do IT
After completing Setup, click Start, click Run, type cmd, and then press ENTER.
In the command window, type help convert and then press ENTER. Information about converting FAT volumes to NTFS is made available as shown below.
Converting FAT volumes to NTFS
To convert a volume to NTFS from the command prompt
Open Command Prompt. Click Start, point to All Programs, point to Accessories, and then click Command Prompt.
In the command prompt window, type: convert drive_letter: /fs:ntfs
For example, typing convert D: /fs:ntfs would format drive D: with the ntfs format. You can convert FAT or FAT32 volumes to NTFS with this command.
Important Once you convert a drive or partition to NTFS, you cannot simply convert it back to FAT or FAT32. You will need to reformat the drive or partition which will erase all data, including programs and personal files, on the partition.
