Guyz... Due to some software requirement or any reason you people need to convert a FAT partition to NTFS. But you don't know how to convert it without formatting or any data loss. So don't worry just be happy becuase the solution is right here.
1. Firstly move on to command prompt by typing "cmd" in Run
2. Enter the command "convert c: /fs:ntfs" to convert the C: partition from FAT32 to NTFS.
Where c: is the partition name. You can use any partition name which you want to convert.
