What the additional commands we can pass to the module? There are a few parameters we can use to make sure it also defrags the boot files.
#Contagious disk map windows
Disk Defragmenter doesn’t defrag the following files: Safeboot fs, Bootsec DOS, Safeboot CSV, Hiberfil sys, Safeboot RSV, Windows page file and Memory Dump.This is understandable as you will be wasting your resources if the file was to be deleted anyway in the end. Disk Defragmenter doesn’t defrag the files present in the Recycle Bin.Disk Defragmenter will not defrag the files which are already in use.
#Contagious disk map free
It carries on doing this until there are no free spaces left on the disk. This makes the free space bigger until it is large enough to move the first file there in one contagious piece (contagious means not breaking the file down and storing it as a whole). If not, it finds the file next to the free space and moves it somewhere temporarily. If the free space is large enough, it directly stores the file there. It chooses the file from the first free space to move. You will need to pass on a specific command to make sure it does (-w as explained later on).īefore the computer can start defragging your drive, it needs to make a map of the whole disk especially all the empty spaces and the files sizes. This means that large files such as games and movies won’t be defragged using the default defragmentation. Fragments of this size already contain at least 17000 contiguous clusters. What are the mechanics of Disk Defragmentation?īy default, the defragmentation tool will only defrag the files which are under 64 MB of size. Disk defragmentation tries to eliminate this extra time taken. This will effectively increase the file access time. The head would have to change its location again and again to read a file. Now imagine if the drive on your computer had files saved with many spaces in between. The head must then traverse through the disk to that location and read the data. It directs the head to a specific location and accesses the data saved there. The operating system has a mapping of all the files and where they are saved. Your hard drive consists of a head from which it reads the data. This makes file retrieval on your system much faster. This means that your entire drive becomes filled with empty spaces.ĭefragging your disk is the process of eliminating all random free spaces, then collecting all the files and saving them in contiguous blocks of memory. If there is space on the disk which has never been used, it preferably saves the file there. However, some operating system doesn’t do this at first. Some of it is stored there while the remaining part is saved in the next free location. If that free space isn’t big enough to accommodate the file, the file is broken down. When you save a file, it’s put in the first available free space. When you erase a file from your computer, its space is marked free.
