Is your Mac Slowing Down – Time to Defrag your Mac Drive / Mac files

After using your Mac system for months or years, the system appears slow and takes more time to open/save a file. Even, you may witness that your system is taking significantly longer boot time than before. The primary reason behind slowing down of your Mac system is the fragmentation of files on the hard drive.

The operating system takes more time to read the fragmented files and thus the data access time increases. However, you can run Stellar Drive Defrag utility to defrag files on Mac and improve your system performance as before.

When you try to save a file on your Mac system, the operating system looks for a memory chunk that is equal-to or greater than the size of the file and stores the same at that location. If the OS does not find a memory chunk of the required size, it breaks the file into pieces and stores at different locations. Such files, which are stored in multiple pieces on the disk, are called fragmented files. While reading a fragmented file, Mac has to gather information from different locations and the access time becomes more.

It is due to several instances of file creation, deletion and shifting operations, the memory of your Mac hard drive gets fragmented and the OS does not get a contiguous memory location to store a new file. In any such conditions, in order to defrag Mac files and make the system run faster, you can use Stellar Drive Defrag utility.

Stellar Drive Defrag provides various defragmenting options to defrag. Below screen shots will give you an idea on how to use the software:
