Windows 7: How to delete the hard disk partition

Sorry and delete this thread if it is re post, but I searched and didn't find appropriate solution for my problem in our forum.
When I bought my laptop, there were only two drives C: and D:
who shared 500 GB equally.
Then I made the partition of my laptop's hard disk drives in to 4 parts during installation of windows 7 ultimate.
C: 30 GB
D: 98 GB
E: 105 GB
F: 232 GB



Now I want only two drives C:120 GB and D:380 GB
Is it possible ?
Please help me to do this

Hi, follow this tutorial to delete the partition
Partition or Volume - Delete

And this tutorial to extend the existing partitions Partition or Volume - Extend

Yes it's possible, just download "partition magic" from here Download Partition Magic 8.0 than open the program and choose there the partition you would like to delete, and its just adding the space of the partition that you erased to another one... when you rebooting (you have to) don't be panic if you see some white screen with loading bar, its normal for this process... hope it helps

The video at the following link provides a good explanation on how to combine partitions;
