    Re-size C partition in Windows 7


    Hello,

    Is there any built-in tool to re-size the C partition because it runs out of space with Windows 7?

    I installed PartitionMagic but it doesnt work on Windows Vista/XP so any software or an idea to do that?

    Thanks

    The best option for resizing any OS primary is using a 3rd party tool without first loading the OS installed on the partition itself. The good freebie GParted live for cd seems to work well for partitioning drives for a variety of OSs including all versions of Windows. GParted -- Features

    Once booted live on cd there's no OS to get in the way. The latest release of the free Linux drive tool is found at SourceForge.net: GParted: Files

    If you have never the Gnome Partition Editor you will want to look over the general information seen at GPARTED DOCUMENTATION - GENERALITIES

    I agreed about the 3rd party but I already installed the OS so is there any free tool to do the extend?

    The unallocated space must be to the immediate right of the drive being extended. The only way to do this in Windows is to shrink D:/Format the new space. Move files from D: to the new space. Delete D: and extend C: If you have a lot of data on D: this may be prohibitive. Third party apps should be able to do this without loss of data.

    Not work! Did you try it and work?

    Check the pic. below:





    I can only create new volume with the free space.

    Hmmm. I see that delete volume is greyed also. Try turning it into a useable volume (give a drive letter, might have to format also) and then see if you can delete the volume. When it is unallocated space, you should be able to extend C into that space.

    The reason why you are having problems is because the partitions are not contiguous. A way round it would be to create a partition on D, move the existing contents of D to the new partition and then extend C into the space previously occupied by D. Finally, rename the partition that now holds the contents of D as D as it will have been given another letter during this procedure.

    Shrink D Partition or Volume - Shrink

    Copy contents of D over to new partition after you have formatted it. Accept the default drive letter - you can change it to D after you have carried out the next step.

    Delete old partition D Partition or Volume - Delete

    Extend C into newly unallocated space Partition or Volume - Extend

    Clarification: Although the procedure in this post is correct (to the best of my knowledge), I was writing and posting it BEFORE I saw the preceding 2 posts. In fact, the most recent post in the thread at the time was this one, which is what I based my reply on.

    Hi iraq it,

    Having examined the image you posted, and carrying out some tests on my external HDD, I can see what the problem is. You are trying to extend a primary partition into an extended one - this cannot be done. An extended partition is simply a container for one or more logical drives. Notice how there is a dark green box surrounding your free space and your logical drives.

    The only way that you can achieve what you want is to copy the contents of the logical partitions onto an external HDD, delete each logical volume in turn, delete the free space and then finally delete the extended partition. Once this section has turned black, you can then extend C into it by however much you choose, upto the maximum space available.
