    Resize ( down) VM

    Hello,
    I have copied 4 GB file into my VM and host Windows started
    complaining about disk low space, so I deleted that file in VM.
    However that did not satisfied my host, and VM reboot and finally VM
    shutdown did not help.
    How can I restore my VM to the previous size?
    Thanks, Claire

    You need to compact the VHD to reduce the size of it.
    Step 1: Precompact. Mount the precompactor.iso from \program
    files\microsoft virtual pc\virtual machine additions, and run it.
    Step 2: Compact. Shut down the VM, run the Disk Wizard and compact the VHD.

    You can get the detailed steps in the VPC help. Start VPC , go to help, type
    "compact" and the first help result will give you step by step instructions
    for compacting

    But isn't there a requirement for doing this that there is at least as
    much free space on the host drive as the original size of the VHD
    file?
    If so then the OP is hosed unless he supplies extra drive capacity...

    Bo, I think you're correct. Its been a while since I've used VPC 2007,
    moved to Windows VPC on Win7.
