What is a defragment?

Boot Defragment is a special version of the defragmentation function on computers. It specifies data, so the files used during the introduction process are physically side by side on the hard disk. This can speed up the start process.

Defragmentation involves regrouping physical data placement on the hard disk. It will cancel the fragmentation that is due to the fact that when a piece of data is removed from the computer, the resulting gap will not be filled in unless another piece of data to be written is not suitable for the gap. This can lead to data arrangement in an inefficient way. This means that the computer has access to each piece of data faster: the difference is only a small fraction of a second, but everything is mounted up. This process is somewhat like cleaning things scattered on the bedroom floor. Once it is done, it is much faster to find the wags Reach each particular item.

Boot Defragment performs the same task, but specifically deals with boot files. These are the first files to load when the computer starts. They areThe files needed to load the operating system into the computer's memory, along with the files to start any program that the user has set automatically after starting his computer.

Because Windows XP operating systems are set to automatically start the introduction of the defragment. It is not controlled by the user and instead runs when the computer is idle for a period of time, usually between five and 30 minutes. Boot Defragment runs in the background, which means the user is not aware that they are running.

Although the boot crush is set to start by default, it is possible that it is unintentionally turned off, for example by application. A user who is self -confident enough to start the Registry Editor can check whether this has happened and turn it on if necessary. This is done by opening the registry editor and switching to HKEY_LOCAL_MACHINE \ Software \ Microsoft \ Dfrg \ Booptimizefunctihe and then check that the value next to the "permit" is set to y rather than n.

While the user cannot directly force the crushing boot to run, there are two indirect methods. One is simply to leave a computer without applications running for at least half an hour, causing the computer to start the defragment if the function is on. Another is to force the computer to trigger all the tasks set to start when it is idle, which includes a boot defragment. This can be done in 32 -bit Windows releases by clicking on the start, then starting, then entering the Rundll32.exe advi32.dll, Processidletasks and clicking OK. Since it does more tasks, it will probably affect the performance of the computer until these tasks are completed.

Apple Mac has no built -in gmentation defrapers. By official recommendations, if the disc is too fragmented, the content backup is, use the MAC initialization function on the disk, and then restore the data. SinceIt is more difficult to perform, it is best stored for serious cases of fragmentation. File management systems in recent editions of Linux -based operating systems do not have built -in defragmentation functions. There are a number of third -party applications that may defrag Linux -based unit.
