Disk Defragmenter (DFRG.MSC) tutorials

  • When you create a volume, Format It and then start using it by creating new files, folders & sub-folders on the available free space, Initially data written and maintained in contiguous blocks.

  • As you use disk for Creating new files, Modifying it, Deleting contigously, fragmentation of file system occurs. Similarly as volume fills up with data and other files, continuous area of free space reduces. This forces the Hard-disk to save remainder of files in non-contiguous area.

  • While referring those fragmented files, Hard-disk Read/Write head have to shift head position from one sector to another sector – leading into performance delay. Although NTFS file system is more efficient at handling disk fragmentation than earlier file systems, this fragmentation still causes performance problem.

  • Window helps in reducing impact of Disk Fragmentation. It optimize volume and rearranges fragemented data in optimal method by joining fragmented files. And in turn it improves hard disk performance.

  • On FAT16, FAT32 & NTFS files and folders are stored in units called “CLUSTER”. Only one file can be written on one cluster.

  • The default size of NTFS is 4 KB. So file up to 4 KB or smaller is written on a single cluster and files larger than 4 KB are written on multiple Clusters. Due to constant operation of Read / Write some files are not written in sequential cluster and these files are broken and written on different clusters. Disk Defragmenter will Analysis and solve such problem.

 

MY COMPUTERS à Select C: / D: / or any HDD drive à Right Click à Properties

  • Select TOOLS à DISK DEFRAGMENT

  • select “Analysis” to Analysis and check files report.

  • “DEFRAGEMENT” will combine fragmented files into normal file and Hard disk read/write performance will improve.
