How To Disk Defragment In Windows 7
How to defrag Windows 10 and Windows viii PCs
Defragging your hard deejay on Windows 10 and Windows 8 is straightforward, and it helps get the files on your hard drive in order. Here's how to defrag a computer:
-
Click the Kickoff button in the bottom-left corner of your screen and type the give-and-take defrag.
-
Then select Defragment and Optimize Drives from the list of options.
-
Click Optimize. This analyzes the disk's fragmentation level and launches the defragmentation process. This can have a few hours to finish. While in process, don't do much piece of work on your PC, bated from possibly some light browsing.
-
When the defragmentation process is washed, you'll see OK in the Current status column, as shown above.
How to defrag Windows seven PCs
Here's how to defrag your reckoner's disk drive if you're running Windows 7:
-
Click the Commencement orb in the bottom-left corner and type defrag.
-
And then select Disk Defragmenter from the search results.
-
Click Defragment deejay to launch the defragmentation process.
If yous have a lot of files on your system, or if your computer hasn't been defragged in a while, this could have up to a few hours. Let information technology run and don't interfere with it — leave your PC lone.
Use a third-party defrag utility
Using third-party utilities and PC optimizer tools makes defragmentation — and PC cleaning overall — a lot easier by automatically handling routine maintenance. These tools diagnose issues and prescribe fixes, saving you from having to deal with defragmentation and other fourth dimension-consuming cleanup processes yourself.
Avast Cleanup is packed with features for speeding upward your reckoner and fixing annoying issues. With Avast Cleanup's dedicated defrag program, you can service your hard drive at the click of a button, or even fix the defragmentation process to run regularly and automatically, and then you don't have to call up near defragmentation e'er once again.
What is deejay defragmentation?
Defragmentation organizes storage on your estimator by consolidating files and other information saved on your difficult bulldoze. When in that location's not enough space on your disk to store an unabridged file in one identify, the file is cleaved down into smaller pieces called fragments. Defragmentation puts those pieces back together.
What does defragging your calculator do?
Defragmentation reverses the process your computer uses to suspension upwardly data when information technology saves files to your difficult drive. Defragging reformats your drive, reconstituting the files that were fragmented when they were written (saved) to your disk.
To understand how defragmentation affects your PC's performance, let'southward look at the anatomy of a traditional hard disk. A hard drive is made out of mechanical components, with multiple discs stacked on top of one another and rotated through a spindle. These discs — also called platters — contain data. To recollect data, your calculator accesses the discs using the read/write heads (like to your grandparents' vinyl record histrion).
Over time, the amount of fragmented data spread over a difficult drive's mechanical components tin can grow alarmingly high. Defragmentation puts those separated pieces of data back together again. The event is that files are stored in a continuous fashion, which makes it faster for your computer to read the deejay and call back the files you need, increasing the overall performance of your PC.
Figuring out how to defrag a computer seems like an unnecessary task these days. "Defrag your disk" sounds like ancient advice, a recommendation you lot'd get back when it was mutual to run Windows 98 on an sometime Pentium 2 computer. Dorsum then, "Defrag!" was regular advice when your system slowed to a crawl. But fifty-fifty though people don't talk nearly it anymore, defragmentation is all the same necessary for ideal performance, and it can salve you lot from having to wipe an old hard drive just out of sheer frustration.
Defragmentation takes the scattered information in your hard drive (above) and organizes information technology (below) for more than efficient retrieval.
The departure between SSDs and HDDs
Difficult deejay admission is a highly mechanical process, fifty-fifty though then many other computer components are purely digital. And disk access is the slowest part of computing. It tin can typically take 5-15 milliseconds for your figurer to access the bits and bytes on a traditional hard disk drive (HDD), whereas accessing data on a modern solid state disk (SSD) or in RAM is done in a fraction of a millisecond.
Aside from the time information technology takes to access files, the overall throughput of hard disks is as well low. Typical HDD speeds are 100 MB/sec for larger files and 0.5-ane MB for small file fragments (which are more mutual in day-to-day operations). Check out our detailed guide to learn more about the differences betwixt SSDs and HDDs.
But the cardinal takeaway is that quondam-school HDDs are extremely slow. So slow, in fact, that the residual of your system has to await a while for the difficult disk to read data. Information technology'south particularly noticeable when you starting time Windows, launch programs, or open big files. That'southward why operations tin experience very slow on PCs with a hd (which are yet fairly common).
A fragmentation primer
In theory, any file on your difficult disk could be stored in a continuous style on a platter. Perhaps, when your computer is make new, saving files starts out that way. But as y'all move, delete, and re-create files regularly — and uninstall programs — file sizes abound. Then, with all the additional information, your entire file no longer fits in the original infinite it was allocated to. The result is gaps, empty spaces on your hard disk, considering your files need to be cleaved upwardly in society for all the data to be saved.
Imagine you make clean up your computer by deleting 5 GB of data from your hard disk, leaving a five-GB gap in the centre of space otherwise occupied by Windows, your applications, and data files. The next twenty-four hours, you lot download the next hot game, which may be about 20 GB. Your hard disk stores the first five GB of the game in that gap you recently freed upwards, and it breaks upward the remaining 15 GBs into fragments and stores them into other gratis spaces or slots them at the terminate of the occupied disk space.
Now your new game is divide up, or fragmented, into two or more pieces. The read/write head of your mechanical hard deejay now has to piece together the files for the game when you lot launch it. Stitching those files together takes more time than it otherwise would if the data were kept in one continuous block of information.
That'due south an oversimplified example. On a freshly formatted difficult drive and cleanly installed Windows PC, the fragmentation level is near zilch. But in reality, your computer winds up with loads of free spaces. The operating organisation splits upwards data and programs into so many pieces information technology makes your head spin, and then you should examination your difficult drive regularly to make sure it'southward still healthy.
DOS or Windows 95 used to evidence the gaps on your difficult deejay and how it was being put together. These old DOS and early Windows utilities no longer exist, simply the concept and process remains.
How often should you defrag your calculator and when?
Well-nigh Windows versions (like Windows seven and Windows 10) defrag the deejay automatically on a regular ground. But if yous're constantly working on your auto, Windows never gets around to this background task. That's why knowing how to defrag a calculator is helpful — you tin can run the defragmentation process yourself (see steps above) and check on the fragmentation status.
On one of my computers, the automated defragmentation procedure hadn't run for 12 days and was 25% fragmented. That had a negative event on performance, and defragging resulted in immediate and noticeable benefits.
Other ways to speed upward your figurer and boost functioning include using a registry cleaning tool or pausing groundwork processes to reduce PC fan noise.
Is it safe to defrag? Can I defrag an SSD?
Defragging a traditional hard disk bulldoze is safe and easy, and it keeps your deejay salubrious. Regular defragmentation and other maintenance tasks help your computer run smoothly, and the risk of damage to your hardware or files is extremely small, even if the process is disrupted mid-flow.
Simply there's no need to defrag an SSD. And don't worry if you're non sure whether y'all accept an SSD or an HDD. When you launch the defragmentation process, Windows will tell you whether it'southward looking at a hard disk or an SSD. If you lot take an SSD, the Optimize button on the defrag screen will perform a so-called TRIM operation instead of a standard defragmentation.
TRIM tells the SSD which information blocks are no longer needed and can be reused (after you lot've deleted a file, for example). The next time an awarding writes data to storage, a data block doesn't need to be erased first to create room. That's ane manner that SSDs improve performance and reduce wear and tear.
Maintain reckoner performance afterward defragging
Defragmentation is a great identify to start, but it's just one office of practiced Windows hygiene. To more than completely clean up and optimize your computer, go a software tool to have care of the work for y'all. Avast Cleanup is a lite and powerfully constructive tool that will streamline your computer automatically. Articulate out gigabytes of unnecessary files, remove bloatware, and get automatic maintenance to proceed your PC running smoothly.
