    inconsistent disk space reported

    Hi,

    Before working on this I did things such as rebooting, refreshing file manager, viewing the disk size in Computer Management->Storage->Disk Management.

    The disk space being reported on my C drive has been inconsistent the past couple of months.
    For example, the C drive indicated I had 4.44 GB free of 917 GB.
    So, I moved 3.6 GB to another computer.
    Then, the C drive indicated I had 92.5 GB free of 917 GB.

    Can anyone think of a reason for this inconsistency?

    Thank you for your time and assistance.

    I would run chkdsk /r on your C drive.

    Running chkdsk would be good. defrag might also be good. Most HD manufactures have programs to test their drives.

    If you suspect there are errors on your drive, defrag is not the tool to run.

    OK !! Then I need to stop W10 from defraging every Wednesday. Is there a reason not to defrag??
    I never heard that you should not defrag. I'm always wanting to learn new things!
    Thanks for your reply!

    The key phrase in @satrow's post is if you suspect there are errors on your drive....

    Defragging a slightly corrupted file system could cause extensive corruption and data loss.

    Windows needs a minimum amount of disk space to be able to work and if you have too little it may not be able to perform its normal maintenance. Once you cleared some space Windows was able to finish what it was doing and clean up, so you now have more space free.
    The moral is, keep more space free.

    cheers, Paul

    Run the drive maker's diagnostic app downloaded from the maker's support site.

    Please don't accept any offers to "fix" the drive without backing up and verifying the backup first. If the drive is "fixed" replace it ASAP.

    Be prepared to write info down. Do not run any write tests...usually the dx app will only run read only tests (unlike CHKDSK) that are less likely to destroy data on a possibly defective drive. A SMART result might be interesting. Best to plug a flash drive in before booting so you can save any results to it (if possible).
