Hello I'm having some space trouble here, just got a used gaming PC and the C drive is almost full.  The files were cleared out by the previous user, but I see that most of the free space came on the D drive, it's a much larger partition.

The Disk 0 partitions are looking like this.

800MB Healthy (Recovery Partition)

260MB Healthy (EFI System Partition)

Windows (C:) 150.00 GB NTFS Healthy (Boot, Crash Dump, Primary Partition)

there was another small recovery partition here, but I deleted it and added the space to C:

Data (D:) 661.61 GB NTFS Healthy (Page File, Primary Partition)

(J:) 97.66GB NTFS Healthy (Primary Partition)     I made this one from D:, and copied the files from D: to J: as a backup.

21.08 GB Healthy (Recovery Partition)

Now I don't know much about this, but for what I've read online.  I know you can only extend the space directly to the right of a partition.

I used the delete partition override in command prompt, to delete the extra recovery partition after C: and absorb that space in to C:, but  I can't do the same with D:

I made the J: partition to try something.  Copy the files from D: to J: and delete D:. Add that free space to C: and create a new smaller D: from C:.  Copy the files from J: back to D:, Delete J: and add the free space back to D:.  That should let me add space to the left to make a larger C: partition, but I can't force delete D:, because of a delete partition override not allowed error, on the current boot, system, Pagefile, crashdump or hibernation volume.

I want to change the Pagefile assignment to J: with the copied files in there, while I fix the size of D: and set it back to D: when I'm finished.

Can I do that, and how?

Any other ideas?

For future reference there is a much easier way to do this.  There is a free 3rd party app called EASEUS partition magic free.  It can merge partitions that are not contiguous.  Unsure what state you are in now.

Well I tried this program you suggested, and it gave me a warning saying that merging the D drive with the C drive may cause a boot error and data loss, so I cancelled the operation.

If I take some space out of the  D drive, then it won't let me select the freed space to merge with the C drive.

EaseUS Partition Master Free Edition

Looks like Magic / Master is the same thing, but all I see is Master on the EaseUS website.

Now I'm getting a bunch of ads btw...

Hi, Gabe687,

How about your problem now? The warning: "merging the D drive with the C drive may cause a boot error and data loss" because of when extend system drive partition, Windows boot file might be corrupt.

To reduce C drive capacity, you can try to make Disk Cleanup for test.

Right click C drive, choose Properties, Disk Cleanup.
