A disk defragmentation software is a program which gives you the optimum utilization of the space in your computer or hard drive. When our computer writes data into a file on our hard drive, it’s not always able to place all of the data together. A section of a file might be written at the beginning of the disc, the rest of that file could be written near the end. Due to this, programs runs slowly because computer spends time retrieving the file fragments from all over the disk. Disk fragmentation leads to system slowdowns, PC crashes, slow startups and shutdowns. Defragmenting the disk arranges files and free space in an orderly manner, reducing the time taken to read a file.
