Description
In the context of administering computer systems, defragmentation is a process that reduces the amount of fragmentation in file systems. It does this by physically organizing the contents of the disk to store the pieces of each file close together and contiguously. It also attempts to create larger regions of free space using compaction to impede the return of fragmentation. Some defragmenters also try to keep smaller files within a single directory together, as they are often accessed in sequence.
Disk Defrag will speed up your computer by optimizing file system. It can defragment files, consolidate free space and move system files to the faster part of the disk.
With AML Free Disk Defrag you'll get the maximum out of your hard drive performance. It is supplied with a powerful engine and smart algorithms which allow Disk Defrag to run much faster than similar tools
Disk fragmentation leads to system slowdowns, crashes, slow startup and shutdown, and sometimes to system failures. Use AML Free Disk Defrag for optimizing the latest hard drives.
Disk Defragmentation Control
Click Analyse button or type F1 to start the volume analysis. Click Defragment button or type F2 to start the volume defragmentation. Click Optimize button or type F3 to start the volume optimization. Use Stop button or F4 hotkeys to stop the currently running disk defragmentation/analysis job.
The progress and status bars located in the bottom part of the window are displaying the progress of the currently running job.
Why are some of the files skipped by the program?
Sometimes Disk Defrag skips certain files because they are locked by another running program. Common solution would be to exit all running applications when you defragment your disk. Some files (MFT, etc.) are skipped because they are system files and cannot be defragmented by this program.
Disk Defrag also needs a contiguous disk space for each file to be defragmented. If your disk has a lot of free space, but it is broken into small free space intervals, Disk Defrag is unable to defragment some of the large files (such as movies, etc.). To tackle this problem, you can first run 'Optimize' and then 'Defragment'. It will consolidate free space into a contiguous block and defragment even the largest files on your disks.
What is MFT?
Probably the most important of the key system (metadata) files that define an NTFS volume, the Master File Table or MFT is the place where information about every file and directory on an NTFS volume is stored. The MFT is in essence a relational database table, containing various attributes about different files. It acts as the 'starting point' and central management feature of an NTFS volume--sort of a 'table of contents' for the volume, if you will. It is somewhat analog to the file allocation table in a FAT partition, but is much more than just a list of used and available clusters.
