Can I convert FAT to NTFS with the convert command

When convert is done, the size of each cluster must be 512 bytes, regardless of how large the partition is. Why, in fact, programmers are too lazy to think too much, directly into the size of each sector 1 clusters the simplest, but the problem is that the file system cutting unit is too small, too loose. Management efficiency will be reduced, addressing can not be in large chunks, efficiency and security are not too good.

So if fat turns to NTFS, it's best to copy the data, format it to NTFS, and then copy it in. This cluster size is effectively set by partition size and is more evenly balanced.
