This video shows how to convert a fat32 partition into NTFS file system. A limitation of the Fat32 file system is that it will not store files larger than 4 GB (Gigabytes). You need to use NTFS for that partition. However, if you simply re-format the partition, you lose all the data. If you convert it, you wouldn’t have to move all your data off and then back onto your newly formatted partition. I do this using command line on Windows Vista, but the process works on Microsoft Windows Server 2000, 2003, 2008. It also works on Windows 2000, xp, Vista and 7.
