    Provided that the target partitions are of equal or greater size relative to the originating partitions. You cannot image a 100GB partition (with e.g. 20GB of data) and then try to restore it into a 50GB partition. The data would fit but you get problems with the rest of the partition files - e.g. the MFT. For such an operation you have to use cloning that can restore to a smaller partition.

    After reading all the replies, then re-reading the original post, I think what you are seeing is the space used for the page (swap) file. The default setting is to allow Windows to resize as it wants based on your memory size.

    The default values on my 3GB installation are to automatically allocate (which is dynamic and does change), 16MB min allowed, 4218MB recommended and the system at this moment has 2812MB allocated

    Try setting a static page file of an appropriate size. This example is for about 1GB:

    Start > Control Panel > All Control Panel Items > System

    Advanced system settings > (Advanced tab) click Performace SETTINGS... button

    Click the ADVANCED tab

    Click the CHANGE... button under Virtual Memory

    Deselect (uncheck) AUTOMATICALLY MANAGE...

    Click CUSTOM SIZE radio button

    Enter an INITIAL SIZE (MB) value such as 1024 (about 1GB page file)

    Enter a MAXIMUM SIZE (MB) value the same as initial value of 1024

    Click the SET button

    Click the OK button

    System requires a reboot to take effect.

    If you get error/warning messages about page file, increase the size settings.

    Hey thanks for that I think that you might have nailed it.

    Just one issue, as you can see from the screenshot I only have 872 MB memory left in the C Drive (which is having this issue) - say if I made the minimum and maximum to 500 MB would that be enough for the page file?

    Thanks!
