    FAQs

    Does defragging free up space?

    Yes, defragging your PC helps free up space by consolidating fragmented files and reorganizing data more efficiently on your hard disk drive (HDD). As a result, this process helps to clean up your PC and free up disk space. With Avast Cleanup, this process is automatic, safe, and simple.

    How long does defragging take?

    The time it takes to defrag your computer's hard disk drive depends on the drive’s size and condition. Smaller drives typically finish faster, while larger or heavily fragmented ones may take longer. Plan for a timeframe of at least one hour up to around 10 hours, but it could be faster or longer in rare cases.

    Can defragging hurt your computer?

    Yes, if you have a solid-state drive (SSD), defragging can actually harm it. You should never defrag an SSD. Most modern Macs have SSDs, as do many Windows PCs. Always check what type of drive you have before considering defragging. Learn how to clean up your Mac with simple cleanup tips or by using one of the best Mac cleaner tools.

    How good is Windows 10 and 11 defrag?

    The built-in Windows 10 and 11 defragmentation tool is adequate for most everyday users. It’s very easy to use and typically handles routine defragmentation for HDDs with moderate fragmentation well. However, it can struggle with severely fragmented drives, and lacks advanced features found in many third-party defragger programs.

    How do I defrag my phone?

    You shouldn’t defrag a smartphone, since defragmentation is only beneficial for hard disk drives (HDDs). If you’re running out of space on your phone, you can clean an Android or iPhone in other ways. Start by uninstalling unused apps, deleting media files or moving them to cloud storage, clearing the cache on your Android or iPhone, and deleting downloaded files you no longer need.
