Disk Defragmenter is a utility in Microsoft Windows designed to increase access speed by rearranging files stored on a disk to occupy contiguous storage locations, a technique called defragmentation. Defragmenting a disk minimizes head travel, which reduces the time it takes to read files from and write files to the disk. Beginning with Windows XP, Disk Defragmenter also reduces system startup times. As of Windows 1. Defragment and Optimize Drives. Early historyeditAs early as the end of 1. IBM PC DOS operating system that shipped with early IBM Personal Computers included a Disk Volume Organization Optimizer to defragment the 5 inch floppy disks that those machines used. Microsofts MS DOS did not defragment hard disks. Several third party software developers marketed defragmenters to fill this gap. MS DOS 6. 0 introduced Defrag. Windows NT, however, did not offer a Defrag utility, and Symantec was suggested as a possible source of the utility. Initial releases of Windows NT lacked a defragmentation tool. Versions through Windows NT 3. Executive Software, later renamed Diskeeper Corporation, released Diskeeper defragmentation software for Windows NT 3. NT kernel and file system drivers that could move clusters. Microsoft included file system control FSCTL commands to move clusters in the Windows NT 4. NTFS and FAT3. 2 partitions. However, Windows NT 4. Disk Defragmenter also shipped as part of Windows 9. Windows 9. 8 and Windows Me. It could be scheduled using a Maintenance Wizard and supported command line switches. This version had the limitation that if the contents of the drive changed during defragmentation, it rescanned the drive and restarted the process from where it left off. The Disk Defragmenter in Windows 2. Diskeeper, licensed from Diskeeper Corporation. It uses the following techniques 3Moving all the index or directory information to one spot. Moving this spot into the center of the data, i. Moving infrequently used files further from the directory area. Obeying a user provided table of file descriptions to emphasize or ignore. Making files contiguous so that they can be read without unnecessary seeking. In Windows 2. 00. Disk Defragmenter has the following limitations It does not defragment files residing in the Recycle Bin or files that are in use. In particular, this includes the registry, page file and hibernation file. Prior to the Windows Vista release, only one volume could be analyzed or defragmented at a time and only one instance could run. Only local volumes can be defragmented network volumes are not supported. The GUI version prior to Windows Vista cannot be scheduled. However, the command line utility since Windows XP and later can be scheduled. Unlike previous versions, the GUI version in Windows Vista does not display a map of disk fragmentation, nor does it display progress during defragmentation. In addition, the Windows 2. Play Sims 3 Online Hacked Sniper. Windows XP 7Defragmenting NTFS volumes with cluster sizes larger than 4 kilobytes KB is not possible. It is not possible to perform fine grained movement of uncompressed NTFS file data in Windows 2. Moving a single file cluster also moves the 4 KB part of the file that contains the cluster. EFS encrypted files are not defragmented. Windows XP and Server 2. Windows Disk Defragmenter was updated to alleviate some restrictions. It no longer relies on the Windows NT Cache Manager, which prevented the defragmenter from moving pieces of a file that cross a 2. KB boundary within the file. NTFS metadata files can also be defragmented. A command line tool, defrag. Task Scheduler. In Windows XP, if the Master File Table MFT is spread into multiple fragments, defrag. GUI version can combine the MFT fragments during defragmentation. Windows Vista and Server 2. In Windows Vista, Disk Defragmenter includes an option to automatically run at scheduled times using Task Scheduler and uses low CPU priority and the newly introduced low priority IO algorithm so that it can continue to defrag using reduced resources less CPU and disk readwrite activity when the computer is in use. The user interface has been simplified, with the color graph, progress indicator, disk analysis and fragmentation information being removed entirely. If the fragments of a file are over 6. MB in size, the file is not defragmented if using the GUI Microsoft has stated that this is because there is no discernible performance benefit since the time seeking such large chunks of data is negligible compared to the time required to read them. The result, however, is that Disk Defragmenter does not require a certain amount of free space in order to successfully defrag a volume, unlike performing a full defragmentation which requires at least 1. The command line utility, Defrag. This utility can be used to defragment specific volumes or to just analyze volumes as the defragmenter would in Windows XP. Disk Defragmenter is maintained by Microsofts Core File Services. The Windows Vista version has been updated in Windows Vista SP1 to include the improvements made in Windows Server 2. The most notable of these improvements is that the ability to select which volumes are to be defragmented has been added back. Notably, the Windows Vista defragmenter is much more effective than the version included with XP. Windows 7 and latereditWindows 7 reintroduces the analyze function and showing percent complete of the defragmentation, both of which were removed in Windows Vista. It can also defragment multiple volumes simultaneously. According to Scott Hanselman of Microsoft, Windows 7 and later do defragment a solid state disk SSD but in a completely different way. There is less incentive for defragmentation of SSDs because file fragmentation has less performance impact on them and they handle a finite number of storage cycles before their lifespan expires. However, file systems cannot support infinite file fragmentation as they reach their metadata limit. In addition, Disk Defragmenter is also responsible for performing the TRIM command on SSDs.

The famous Ophcrack is used for recovering the password. Even i have posted about using Ophcrack. But the problem is that its bulky in size. We need to download a file of size 5.
