Day by day pass, one by one those thing move out or children played with their toys and it’s become messy. At the first day you move to your new house, everything takes places neatly and accordingly.

In a house concede of many things, such as furniture, kitchen stuff, toys for child, and etc. In the different way, I will put a house as an example. Larger files and greater numbers of files also contribute to fragmentation and consequent performance loss. Fragmentation happen if the operating system unable to or will not allocate enough contiguous space to store a complete file as a unit, but instead puts parts of it in gaps between other files (usually those gaps exist because they formerly held a file that the operating system has subsequently deleted or because the operating system allocated excess space for the file in the first place). Stack memory does not suffer from fragmentation, because blocks must be freed in the reverse order they were allocated.What does defragmentation do to computer system?ĭefragmentation is a process that reduces the amount of fragmentation in file systems inside a laptop or desktop.
#Help me defrag my computer free
You scan the record of which blocks are free and which used. * Obviously you don't actually scan the disk everytime you want to save a file. SSDs are less affected by fragmentation, and in fact you should not defragment them, as defragmentation involves lots of reads and writes to the drive, and SSDs can only be written a limited number of times before they fail. This makes accessing files faster** because the hard drive isn't having to seek so much when it's reading a file, and since file I/O is a very common operation, it will improve the performance of a wide variety of programs.įragmentation can happen to any memory device in which blocks of memory can be allocated and freed - including RAM**, but it is mostly a problem for hard drives because of the long seek time when accessing different areas of a file. This approach reduces fragmentation when possible, but it's not immune- as a disk becomes full, it may be the case that there isn't a large enough free block anywhere on disk, and the file must be split into multiple smaller blocks.ĭefragmentation is the process of rearranging the files on disk such that more of them are in a contiguous order (or at least divided into fewer pieces). Even better, choose the largest block, so that the remaining free space left after the write will be as large as possible. When this file needs to be read, time will be wasted on seeking between different parts of the file and it will take longer.Ī better approach would be to scan the whole disk*, searching for a block of free space large enough to store the whole file contiguously. Unfortunately this leads to bad fragmentation, because files are being split into pieces.

It's the job of the filesystem to determine how to allocate storage for that file.Ī naive approach might be to scan the disk*, write data in the first free block found until it's full, then the next free block, etc. When you delete a file, the space it once occupied is marked as free (the data itself usually isn't erased), and the operating system is now allowed to use that space for storing new files. Therefore, you want fall the data in a given file to be laid out sequentially, so that it can all be read in one go without having to jump around.įragmentation is when this isn't the case - different bits of different files are scattered about the disk. Hard drives are not random-access devices- moving from one part of the memory takes time (called the seek time).
