The hard disk of your computer is where the files are stored, but in the form of small fragments instead of complete units. The operating system, for example Windows, manages the access to these fragments using the location of each fragment. However, as these files are used and eliminated, there are changes in location and organization of the fragments. When disordered, Windows has difficulties to access the fragments, which may cause the system to slow down as the time goes by and more files are added.
To better understand the defragmentation of files, we can imagine an empty room which we must fill with boxes of different sizes. Instead of organizing the boxes, we simply assign each one any space available at that moment. As we add more boxes, we notice that there are empty spaces and that the boxes are all over the room. This disorder is similar to the fragmentation of the files in a hard disk, where the files are divided into fragments and free spaces are assigned, which results in a disordered location and makes it more difficult for the operating system to access the files.
What is involved when a hard disk is defragmented?
To defragment (or defrag) a hard disk is a process that looks to reorder the information stored so that it can be found together and in line. In general terms, the defragmentation is a process which orders the disperse data of a hard disk. It is a way to optimize the location of the files in the hard disk to improve the system performance.
Why do we have to defragment the hard disk?
When you defragment your hard disk, the performance of your PC improves since it allows for a quicker access to the files and folders. When you write, eliminate and change the size of the files, these may end up scattered and disordered, which slows down reading and writing of these files. When a hard disk is defragmented, the process seeks to align the files and put these together, so that these can be found quicker and this way improve the response time of the system.
The reordering of the file fragments makes it easier to access the files, and this allows for the operating system to access these in a faster and more efficient way. The hard disk performance is improved, which translates to a more fluid user experience.
How often do we need to defragment the hard disk?
This is a common question, and a good one. Hard disks are designed to have a long lifespan and to be able to support big workloads. It is important to bear in mind that the defrag frequency depends on the hard disk usage, and the number of changes and updates carried out on the stored files. In general, the modern hard disks have better file storage and management capabilities, which may reduce the need to frequently defragment these.
It is common to see a recommendation to defragment your hard disk once a month, or even every two weeks, in order to avoid the fragmentation from affecting the performance of your system. However, it is worth highlighting that there is no set time period to defragment, and that if your Windows system is configured correctly, the defragmentation may be scheduled to be carried out automatically so that you do not have to worry about this. A scheduled defragmentation is a good way to make sure the hard disk is optimized without the need to carry out this task manually and to remember to do this periodically.
The defrag frequency depends greatly on the usage of the PC. If you use the computer on daily basis, it is recommended to defrag every fifteen days or once a month so that the hard disk performance is not affected. On the other hand, if you do not use the PC that often, the period between defragmentation may be increased, for instance 3 months. It is important to consider that the defragmentation frequency may vary depending on the type of files that are used, and the number of updates that the files experience. It is recommended to check and evaluate the state of the hard disk on regular basis in order to see if defragmentation is required.
