Re-allocating space help needed please

[MPTech]

Trying to help a friend. His PC was setup with 3 partitions: C-Drive (OS), D-Drive (Apps), and E-Drive (Data). Unfortunately, he loaded iTunes to his C-Drive and it has been filling up that partition very quickly and he's about to exhaust the remaining space. I ran CCleaner and TFC to buy him some time. I went into Administrative Tools \ Computer Management \ Disk Management and freed up some of the space from his D-Drive (lots of space available there). I performed a "Shrink Volume" on that partition, but it wouldn't allow me to go back to the C-Drive and extend volume. (It was greyed out and not accessible).

Am I doing something wrong? How can I re-allocate it?

If this doesn't work, I can try running Partition Magic to do it.

Suggestions please.

Thanks!

You would probably need to move the D: partition down so the free space on the drive is between the C; and D; partitions. You would likely need some third party partition software for this. Partition Magic is old, so something newer might be a better choice. You could also re-expand the D: drive and try moving the iTumes library to that drive.

I was kind of concerned that the free space may not be located correctly to extend C-Drive.
I have old software. When I found something that worked, I didn't change it. Reliability was more important than speed.
Can you recommend free software to re-allocate and move apps? (I was using COA (Change of Address), I know that's old too).
I'm always afraid to use software that doesn't come personally recommended.

... Unfortunately, he loaded iTunes to his C-Drive and it has been filling up that partition very quickly and he's about to exhaust the remaining space...

If that is the only reason that his C: partition is filling up,
Configure his iTunes so that all of his iTunes downloads/data is automatically saved/stored to his D: partition.

Usual partition layout would be one for operating system and software
and
One other partition for data.
