    Disk Cleanup takes long time to run


    Hello,

    I'm running Win 10 Pro v1903.
    Always, when I was launching Disk Cleanup, it was cleaning the disk in seconds.

    I've noticed recently that when I launch Disk Cleanup, it takes exactly 3min 56 sec (timed) to run while the elements to be cleaned are empty.

    Is there a way to speed up this process?
    Regards

    Seems like you have selected the wrong drive? I would expect to see C: as the drive you are cleaning?

    Hi,
    I did not choose the wrong disk. For several years no matter the disc selected (SSD or HDD, C: or X:), the cleaning is done in a few seconds. It depends on the size to be removed.
    Today, when I run Disk Cleanup on C: (SSD), the cleaning is done in a few seconds and on K: (HDD) almost 4min. It seems to me abnormal.

    I wonder if there may be a developing problem with the K: (HDD) drive? If so ensure that all files on it are saved elsewhere.

    The operating system drive (usually C:) is the drive that usually gets filled up with temporary files and benefits from Disk Cleanup. Other drives are usually used for storage only and do not benefit from disk cleanup. They will benefit from Defragmenting if it is an HDD and a lot of writing/deleting has been carried out on it but why would you want to run disk cleanup on it? Is there another OS on it?

    Cleaning my C: drive (an HDD) took a few seconds, one to check for files, and a couple of seconds to clean up. My D: drive (another partition on the same HDD) and an external USB HDD took about the same time to check for files, but longer (about 30 seconds) to clean up. None of the drive have disk errors, it seems to be cleaning the Recycle bin on these other drives that takes longer.

    If you clean up System files it will take much longer. This is down to cleaning update backups, known to be a time-consuming process however you start it (you could also use DISM from a command prompt).
