I am in the cmd environment of Windows XP.
How to convert FAT32 to NTFS format without formatting? It seems there is a command starting with c. Please高手 explain the usage in detail. Also, is there a command to convert NTFS to FAT32 format?
Another question: If I convert the C: drive (where the Windows XP system is located) to NTFS format according to the above method, can Windows XP still start normally? Or can I execute this conversion command while Windows XP is running?

Convert FAT to NTFS using the convert command.

CONVERT 驱动器号: /FS:NTFS

Tips: The NTFS converted in this way is different from the one directly formatted. The specific solution is at:

Common partition formats include Fat16/32, NTFS, etc. In addition to selecting when directly formatting, converting partition formats can also be completed with the help of the Convert command. Especially when converting the Fat format to the NTFS format, the Convert command can realize content lossless conversion.
But many friends directly use "Convert X: /FS:NTFS" when converting. Although this conversion is not wrong, it is easy to make mistakes when converting, and even if there is no mistake, its performance will not be improved. Now we will introduce the correct conversion method to you.
We take the partition to be converted as drive E with a size of 20G. First, run the "CMD" command to open the command prompt window, and enter "Fsutil file createnew e:\testfile.txt 2500000000", where 2500000000 represents 12.5% of the total capacity of the partition. You can convert it according to your actual partition capacity. After the command is executed, you can use the built-in disk defragmenter of the system to use the generated placeholder file testfile.txt to perform a comprehensive defragmentation on drive E, and merge all available spaces on drive E into a continuous area.
After finishing the defragmentation, we return to the command prompt window again, and enter "Convert E: /FS:NTFS /Cvtarea:testfile.txt". After the command is executed, the conversion can be carried out. After the conversion is successful, the testfile.txt file will be automatically deleted. In this way, the converted disk space is continuous and complete, and the reading and writing speed can also be improved during access.

Key points

• Before running convert, you must first use the fsutil file createnew command to create a placeholder file. Convert does not create this file. Convert overwrites this file with NTFS metadata. After the conversion is completed, all unused space in this file will be released. For detailed information about the fsutil file command, see "Related Topics".

Wow, the above explanation is very detailed, thanks big brother, I have successfully converted!

But I converted before seeing the above content, 5555555555555555555555555

Is it still possible to use "Disk Defragmenter" now?

By the way, what command is used to convert NTFS back to FAT32 format?

There's no way out～～～～(Thinking: Are you just kidding me～～～)

Unless using PQMagic, but it has poor support for Chinese～

Never use PQMagic to convert NTFS back to FAT32. Chinese characters will become garbled.

You can try Paragon Partition Manager instead.

It's best not to mess around if there's nothing wrong.

Thanks
