$Upcase: Used for converting lowercase characters to the matching Unicode uppercase characters.

$Quota: Disk quota usage for each user on a volume.

$BadClus: Record contains the bad sector location in the volume.

$Boot: This record contains the bootstrap code for the volume, if this is a bootable volume.

Each bit represents a block in the file system, which indicates if that block is free or not. All the folders and files listing ( only listing) come under this. MFT attributes are defined here, allowing extensibility.

$AttrDef: A table of attribute names, numbers, and descriptions.$Volume: The volume name, NTFS version, and other information about the volume.(This will never recover your unsaved data :) ) The rollback operation returns the file system to a previously known and consistent state, as if the transaction had never occurred. On system failure in the transaction, the part that has been completed must be undone or rolled back. All the transactions will be logged before it is performed on the disk. The log file is a system file so that it can be found early in the boot process and used to recover the volume. $LogFile: Log file is to make the file system recoverable.The figure below shows the overall picture of how MFT and system files are organized. The size in bytes per MFT record is indicated in the boot sector (i.e., in BPB). A record of MFT normally spans up to 1024 bytes. First 16 records in MFT are reserved for system files. The first and second records in the MFT are MFT itself and mirror MFT respectively.

Even MFT and mirror MFT have a record in them. What I mean file is system files, directories, normal files, hidden files, etc. The following figure illustrates the layout of an NTFS volume when formatting has finished.ДЄll the files in the NTFS have a record in representing MFT. Normally, the first resides in the beginning, and second MFT, called mirror MFT, resides in the middle part of NTFS disk. Like FAT, there are two MFT for each NTFS file system. Unlike FAT, it can reside any where in the disk. Therefore, whenever system boots up, it reads the boot sector, finds the MFT, and loads it before any file operation. It is a lookup table like FAT (File Allocation Table) in FAT file system. NTFS starts with MFT (Master File Table). NTFS provides several things to Windows than the FAT, for example: Security, Large storage, etc. For explanation of journaling, see the LogFile section below. Journaling file system means it can recover from sudden crashes (may be, Microsoft knows long before, their OS will crash more often :)) ). It is a fast performing and sophisticated file system. Microsoft says NTFS is a fast performing and journaling file system.

This explanation looks kind of an additional patch work for documentations available on the net. I created this tool to satisfy my curiosity, and I'm presenting to all of you having the same interest. There are many tools out in Internet for recovering deleted files from NTFS, but I couldn't find one with source, by now. It is a more sophisticated, powerful and complicated file system than FAT file system. NTFS - 'New Technology File System' is the preferred native file system for Windows NT series.
