Windows 7: Resize C Drive

Resize C Drive

I have Windows 7 64 bit and it has worked fine for a long time. Recently I installed a new program and I got the message that I could NOT run the program because I was low on memory for C drive.

My Hard Drive is partitioned into three partitions C, D and E.

Is there anyway I can reduce the size of D drive and add that reduction to C drive??

Help is appreciated.

I'm afraid not, I believe that in order to change partition sizes, they must be deleted then reformed. You'd have to backup all the data and then format the hard drive - not a good idea.
Did you get an option to change the installation path when you installed the program? If you did, you could just change it to the partition with more space on it.

Alternatively, you could try changing the program file installation directory so new programs are installed to the partition with more space in it, and then uninstall the program and reinstall it. This would be complicated though as you'd have programs on each partition.

Hope this helps,

Hi Huffman,
Have a look at this link, from technet,

Most advocate using Partition magic or gParted in this forum, have a look at them.

This is now possible without having the need to reformat the partition.

I've performed the task using Partition Magic:
Move/Resize Partitions in Single Internal HDD (Repartition)

The above thread contains links to tutorials and screenshots of the ongoing process (so you don't get nervous). Please take time to read the tutorials from the PartWiz website. Their documentation is concise and useful.

Yes there is a free version.

What is it that you cannot follow? The step-by-step process is on their website with an accompanying video tutorial.

Did you follow the link in my thread?
