Currently, we have two types of file systems; FAT and NTFS. As the release of Windows 98, Fat 32 has replaced FAT 16 while NTFS is the latest file system that is extensively promoted by Microsoft, not only fitting large disk but offering richer file functions. Therefore, many users want to convert previous partition file system to NTFS.
Advantages of NTFS
NTFS mainly features in safety performance and stability that hardly produces file fragment. Besides, NTFS records user operations and impose strict limitations over user right by allowing each user to perform certain with given rights to insure system and data safety.
NTFS is a Journalling filesystem and uses the NTFS Log to record metadata changes to the volume. It is a critical functionality of NTFS for ensuring that its internal complex data structures (notably the volume allocation bitmap, or data moves performed by the defragmentation API, the modifications to MFT records such as moves of some variable-length attributes stored in MFT records and attribute lists), and indices) will remain consistent in case of system crashes, and allow easy rollback of uncommitted changes to these critical data structures when the volume is remounted. The USN Journal (Update Sequence Number Journal) is a system management feature that records changes to all files, streams and directories on the volume, as well as their various attributes and security settings. The journal is made available for applications to track changes to the volume. This journal can be enabled or disabled on non-system volumes and is not enabled by default for a newly added drive. Sparse files are files which contain sparse data sets, which are files with segments stored at different file offsets with no actual storage space used for the space between segments. When a file is read back, the file system driver returns zeros for any data that doesn't actually exist, so the file may appear to be mostly filled with zeros. Database applications, for instance, sometimes use sparse files. Because of this, Microsoft has implemented support for efficient storage of sparse files by allowing an application to specify regions of empty (zero) data. An application that reads a sparse file reads it in the normal manner with the file system calculating what data should be returned based upon the file offset. As with compressed files, the actual sizes of sparse files are not taken into account when determining quota limits.
Convert FAT to NTFS
User could use Format command to direct convert file system if the partition contains merely some temporary files. However, Format command is not adoptable if user wants to keep partition data while converting file system since this operation would damage disk content. Here, I would like to recommend a third-party partition manager by the name of MiniTool Partition Wizard. Download at https://www.partitionwizard.com/.
The following is a demonstration on how MiniTool Partition Wizard converts FAT to NTFS.
