*You can use command.exe (convert.ext ):
Start- CMD-type convert disk:/fs:ntfs/-Enter
This process can not damage your data, but it will waste lots of time. When you go on this process, the disk you want to concert file system must have some free space. If there is not much more free space, it cannot be supported to convert. By the way, in different operating system, the convert.ext has different limitation. And it can not be converted back to FAT32.
