Like NTFS, exFAT can pre-allocate disk space for a file by just marking arbitrary space on disk as "allocated". For each file, exFAT uses two separate 64-bit fields in the directory: the valid data length (VDL), which indicates the real size of the file, and the physical data length.
[b] The file system could defragment the disk immediately after a deletion, but doing so would incur a severe performance penalty at unpredictable times. Now, a new file called F, which requires seven blocks of space, can be placed into the first seven blocks of the newly freed space formerly holding the file B, and the three blocks following ...
NTFS metadata files can also be defragmented. A command-line tool, defrag.exe, has been included, [10] providing access to the defragmenter from cmd.exe and Task Scheduler. In Windows XP, if the Master File Table (MFT) is spread into multiple fragments, defrag.exe and the GUI version can combine the MFT fragments during defragmentation. [11]
The problem with missing exFAT support in most operating systems isn't that the internals of exFAT are not known (even if Microsoft hasn't made them available to the public), but that it would be illegal to use exFAT without a license from Microsoft, even if the implementation is not derived from Microsoft's in any way.

We tracked down the week's best deals at Amazon, including an iPad that's $100 off and a range of beauty products that are marked down.
Along with defragmentation, UltimateDefrag performs consolidation of both disk space and files within folders, arrangement of files by volatility (most often used files) or recency (most recently used files), and analysis of the disk. In addition, UltimateDefrag has the ability to defragment files based on manually entered wildcard expressions. [4]
