    So ive had bootcamp for a while, im getting more and more games, and now only have 10gb left. Now, i only have itunes and music on my mac, and use it for photo editing and every day browsing.

    Is there a way to reduce the size of the osx partition, then increase the size of the windows partition, without having to format and reinstall everything

    Yes there is! There's a tool called Winclone that makes this process much simpler. Here's how you go about it:

    1. Boot into Mac OS X, if you're in Windows
    2. Download/Install Winclone
    3. Run Winclone, it'll ask to download the NTFS tools, so go do that
    4. Install the NTFS tools
    5. Run Winclone again, this time clone your Windows partition to an image file
    6. Quit Winclone, run the Boot Camp Assistant
    7. Delete the Windows partition
    8. Create a new, larger Windows partition
    9. Quit Boot Camp Assistant, launch Winclone again.
    10. Restore the clone you made earlier
    11. Go to Tools -> Expand NTFS filesystem to make Windows able to use the new space
    12. Boot into Windows.
    13. Windows will check your disk for errors, then boot normally.

    You need to clone your Windows partition, remove it via Boot Camp, and reinitialize it.


    Scroll down to Changing the size of your NTFS Partition

    Edit: Like he said ...
