    I have vista home premium, 200gb hard drive. i had not been payin
    attention until I received a warning that I was running out of space
    Being sort of a dummy, I took computer to Best Buy. They ra
    diagnostics. They found no problems. Then they cleaned it up an
    optimized it. When I got it home the C drive showed 177gb capacity wit
    135gb free space. Within 3 days my free space was reduced by appro
    25gb. I downloaded and ran Auslogics Defrag and my free space was agai
    135gb. But in the last 5 days my free space has been disappearing. It'
    at 113gb right now. I realize that's plenty of free space, but I'd lik
    to rectify this problem before I'm close to showing full again. Ca
    someone help me

    Hi, Frank.

    This question gets asked often, so Google or Bing should find plenty of
    answers for you. But the answers come in many parts because there are many
    causes for your question - so there are many partial answers.

    Just a few candidates:
    Since files are stored on the disk in fixed-size "clusters" or "allocation
    units", a one-byte file can take a full 4 KB cluster, so many small files
    can take a lot more space than just the number of bytes in the files.

    Deleted files continue to take up space until you empty the Recycle Bin.

    System Restore points can gobble up loads of space, depending on your
    settings in Control Panel | System | System Protection.

    The hidden system files hiberfil.sys and pagefile.sys can take up several
    times as much space as your total RAM.

    As I said, these are just a few possible places to start your research.
    There are many others. Good luck!
