Seven pieces of disk defragmentation software competition and download _ Common Tools

After a hard disk has been in use for a period of time, the free sectors on the disk are dispersed to the discontinuous physical locations throughout the disk because of repeated writing and deletion of the file, thus making the file unable to have contiguous sector classes. In this way, read and write files need to go to different places, to increase the head movement back and forth, reducing the speed of disk access.

The hard drive is like a house that needs to be sorted more often, to defragment the disk we need to use Disk Defragmenter, a disk Defragmenter can defragment volumes that use the File allocation table (FAT) file system, FAT32 file system, and NTFS file system format.

However, some people think that the regular defragmentation of the hard disk will damage the life of the hard drive! Disk defragmentation is the fact that the files on your hard disk are written back to the hard drive to keep the files continuous.

We all know that only a long period of continuous reading and writing hard disk will cause a certain damage, but the defragmentation is not a damage to the hard disk, because most people will not be collated every day, and the time is very short, and not long time to read and write hard disk. You don't have to worry too much about defragmenting your hard drive to make it work. It is recommended to defragment the disk at least once a month to two times to keep the hard drive reading and writing at its best.

The amount of time that defragmentation takes depends on several factors, including the size of the volume, the number and size of files on the volume, the number of fragments, and the available local system resources. First, analyze the volume to find all the fragmented files and folders before defragmenting the files and folders. You can then see the fragmentation on the volume to determine whether it will benefit from defragmenting the volume.

At present, the network available for the choice of disk defragmentation software numerous, today I collected a number of mainstream disk finishing programs, I hope you can choose their own satisfactory defragmentation software.

 
One, Ultimatedefrag green version

Ultimatedefrag is the fastest disk Defragmenter I've ever seen, compact and easy to use, just click "Start." The
supports 4 different types of disk fragmentation increments, with policy file configuration options that allow you to optimize your hard drive for faster access based on file usage.
The software uses only 20% file rules based on 80% of the time for most users, so most of the content on your drive is dormant for most of the time. With advanced disk defragmentation mode, you can specify which files and folders are rarely used and put them on slow tracks on your drive, and prepare fast access areas for files you use frequently.
Ultimatedefrag can automatically locate these files according to the file attributes and access dates that match your criteria. The software interface provides a display that allows you to visualize the contents of a drive and to see exactly where files and folders are located on a physical disk.
Ultimatedefrag does not require you to be an expert, but if you are, you will find that there are many configurable options that allow you to customize the defragmentation process in any way. The software also includes a scheduler for automating disk defragmentation operations and support for features such as disk defragmentation, background disk defragmentation, and so on when the computer starts.
Comments: The operation is very simple, just click one press ashamed. Finishing faster than any software, you can schedule scheduled automatic defragmentation of the disk.

Second, O&o Defrag Professional

A disk tool specifically developed for NT/2000/XP, which can be applied to a variety of editions, such as workstations, servers, and advanced servers, supporting almost all file systems, including FAT16, FAT32, NTFS, NTFS5, FS (Encrypted file system), etc. is a rare and good tool.
can set time to automatically restructure the hard drive, support Chinese long file name and need to install Windows NT Service Pack 4 or Windows 2000. Software requirements for the hardware environment is not high, 486 of the machine, the minimum 16MB memory, VGA display card, such a configuration I think is very easy to meet it.
Defrag can only be executed under win NT/2000/XP and will be prompted with an error message when installed under win 98/95: Unsupported operating system. Because the Win nt/2000 is a multiuser operating system, you must confirm that you have permission to install the software on the operating system before installing the software.
Comments: 5 Kinds of disk defragmentation, optimize the use of space is the best, but the disk defragmentation time is longer.

Third, Diskeeper Pro

The well-known disk finishing tool "Diskeeper", originally for Windows 2000, with the disk finishing tools, but the older version, but also only streamlined, if you want to use a newer and full feature version, this is a full support for all Windows version of the disk finishing tools, integration of Microsoft Management Console (MMC), which enables you to defragment Windows encrypted files and compressed files, and automatically analyze the disk file system, regardless of whether the disk file system is FAT16 or NTFS-safe, fast, and in the best performance state.
You can choose to complete or just clean up the available space, keep the disk files continuously, speed up file access efficiency, there is scheduling disk function, you can set up the disk schedule, time to help you automatically do disk maintenance work.
Comments: Features are very rich, you can schedule scheduled automatic defragmentation disk fragments. But this program has a high CPU share.

Four, Voptxp

as a veteran Disk Defragmenter, VOPTXP is welcomed by the vast number of computer users. The new version of the VOPTXP in the appearance of more friendly, more convenient to operate. Through the drive menu, we can manually select the partition to be sorted out, the main window will be a different color tag to display the finishing process, and will count the size of the fragmentation, disk free space, the number of files, folders, and temporary file Recycle Bin files and so on.
Comments: There are many additional tools, easy to operate. But the speed of finishing is not satisfactory, the stability of the program itself is not good

Five, The defragmenter Disk Defragmenter developed by Defragmenter Pro

Abexo Company is divided into several versions, Pro and Pro plus. The biggest difference between pro Plus and pro is that the former has a cleanup tool that cleans up Internet records, temporary files, and garbage files in the Recycle Bin, as well as removing paging files, hibernation files, running ScanDisk, and disabling screen savers.
Now online has not seen the Chinese version, the author has been in the beginning of the Chinese defragmenter!
Comment on: The defragmentation speed is very fast, the CPU share is low, but its finishing effect is more general.

Six, Perfect Disk

Perfect Disk is the Raxco company's product, which has the most common operating interface and function of Disk Defragmenter software, that is, to analyze the disk first, and then to defragment, whether it is FAT or NTFS-formatted hard disk partitions can be accurately analyzed and maintain hard drive continuity. This software is playing a faster and better than diskkeeper slogan to promote! After trial, this program than that VOPTXP finishing effect is definitely better!
can also through the network connection to the remote computer to do hard disk or floppy disk reorganization function. Whether the disk file is FAT or NTFS format can intelligently analyze the disk file format, secure, fast to the hard disk or floppy disks in different areas of the file and directory for reorganization, keep the hard disk or floppy file continuous, access to the file more efficient.
Comments: Concise layout, software analysis will give a more detailed recommendations. Plus a variety of humanized design, more in line with the use of Chinese habits. Simple to operate, support for network analysis and disk defragmentation, but slightly slower.

Vii. Comparison of alternative defragmentation ghost
If you only use Ghost to back up and restore data, then you can wronged this "powerful" software. In fact, with Ghost can also defragment the hard disk, you know, with Ghost do disk image, Ghost will be hard disk partition every data read out completely, and then write it into a Gho file, for the partition of the blank part, the software will automatically skip.
Then when we restore the Gho image file, the software will continue to write all the contents of the file into the partition, so that all the data will be automatically written on the head of the partition, we get the complete unused space, the original fragmented files will naturally disappear.
The specific ways to defragment the Ghost are: Scan and fix all the error codes on the partition first, then use Ghost to make a gho image file, the size of the file depending on the use of the partition, and then restore the Gho file to the original partition, these operations are best in pure DOS mode operation, Be sure to select the partition when you restore the image, or you will lose the data.
Comments: In pure DOS operation cumbersome, not suitable for the ghost unfamiliar to ordinary users, backup restore time to be careful, easy to cause data loss!

Several issues to be noted before using the finishing process:

First, before you use Disk Defragmenter, turn off all open applications and remember the garbage in the Recycle Bin, because some programs may have to read the data on the hard disk repeatedly while they are running, which may affect the defragmentation process.
Second, the screen saver must be turned off before you can organize your work, or the defragmenter will start again and again.
Third, in order to be able to speed up the system start-up speed, should try to reduce the debris in C disk. When the application requires insufficient physical memory, by default the system generates a file named pagefile on the hard disk system disk, and the hard disk space occupied by the file is virtual into memory, even if we do nothing but turn on the computer and the same file exists.
Virtual memory management programs frequently read and write to hard disks, resulting in a large amount of fragmentation, which is the primary cause of hard disk fragmentation. To avoid a large amount of fragmentation in the frequent reading and writing of temporary swap files in Area C, you can specify pagefile files to be generated in other partitions.
Four, after each use of the browser will produce a lot of temporary files, in order to avoid the browser to read and write these temporary files caused by a large number of fragments, you can designate the temporary directory to other partitions.
Five, if the hard disk space is too small, the speed of running the application will be slow, disk defragmentation is difficult to do. So in the process of using the computer, should release the wasted disk space in time.
