This is because the software copies the fragmented data from the places it is stored into the free space, where it reassembles it.
Then it moves data around on the drive until there is a block of free space available that can hold the data. It then copies the data into this block, and deletes it from the temporary holding space. If your drive is heavily fragmented, this can take a very long time.
Modern file systems - the rules computers use to organize their writes to the disk - are also designed to avoid fragmentation. It recognizes the difference between hard drives and SSDs, and allows you to TRIM your SSDs - a sister process to defragmentation that empties all the space once taken up by deleted data and gets it ready for reuse.
This again improves performance, as otherwise it would need to be done just before new data was written. In addition to ensuring your Windows machine is regularly defragged and running optimally, we also recommend defragging your external hard disk drives HDDs. If you use your external HDD frequently for saving and accessing programs and data, this is especially important to maintain. In contrast, you do not need to run defragging software on a flash drive also known as a jump, USB or thumb drive or on an external SSD.
On a side note, you can save your disk defragmenter software onto an external drive. Keeping your software stored externally can be convenient in case your computer crashes, or in case you travel frequently and want to run the software on multiple computers. You may be curious why this is, but the answer is fairly simple: the file system within a Mac hard disk drive HDD is designed differently from one on a Windows computer.
New Mac OS versions automatically check for fragmentation every time you access a file or program. However, we recommend periodically going through your hard drive to delete old or unwanted files and programs to keep as much space available as possible, or to purchase a larger HDD that better suits your storage needs.
These generally replicate a lot of the native functions, but add more of their own, particularly in the form of SSD optimisation tools that go beyond TRIMming. Whether you need them or not, will depend entirely on individual use cases. Macs in particular have a habit of not defragging properly if the drive is too full. Ease of use What you really want is a program you can set going, and which runs in the background, not bothering you until it announces it has finished.
Some have different options for you to set, but we discovered that all of the apps on test provide comparable results if left on their default settings. Scheduling Being able to defrag outside of your work hours is important if you depend on squeezing every FLOP of power out of your rig. There is a performance penalty, both in terms of processor availability and disk bandwidth, but many users will never notice it.
Other scans Alongside defragmentation, programs may offer registry or driver scans. The same goes for drivers, especially since Microsoft has moved to a new driver architecture that isolates them from the rest of the system. One thing driver scans are useful for, however, is identifying which drivers have updates available.
You have full control over when your disk defragmenter program runs — you can put it on a schedule or use it manually whenever you need. Both options have pros and cons, and learning the benefits and downsides to each can help you use the software the most effective and efficient way for your situation.
Instead, you can rest assured that your hard drive is optimized. Most of the programs we reviewed are easy enough to use, with clearly labeled buttons.
Some even have guides that walk you through the entire process. If you are an advanced user familiar with the ins and outs of this type of software, you are better off running the program manually.
When you run it manually, you also have more granular control over the process, and you can run it on additional external hard drives if you want. Boot time defrag is typically only used by advanced users who are extremely knowledgeable about computers. By definition, boot time is the time between when you hit the power button and when your computer is ready to use. During this time, your computer starts executing instructions such as loading its operating system and connecting with peripherals like the mouse and keyboard.
You have full control over which drives, folders and files you defrag. Or simply use the default settings and let Defraggler do the work for you. Simple enough for every day users and flexible enough for advanced users.
