The NTFS Undelete application was developed to be a tool to undelete a file in NTFS and a short tutorial on NTFS.NTFS - "New Technology File System" is the preferred native file system for Windows NT series. It is a more sophisticated, powerful and complicated file system than FAT file system. It is much efficient for larger disks. There are many tools out in Internet for recovering deleted files from NTFS, but I couldn't find one with source, by now. I created this tool to satisfy my curiosity, and I'm presenting to all of you having the same interest.
