Windows 10 Home has created an extra partition (Local disk 'F'), why?

I recently built a new computer and installed Windows 10 Home and ideally I would have had the following:
Operating System (C), Games (D) and Everything Else (G) - C and D on my SSD and G on my HDD.

However, after the install, a disk 'F' appeared on my SSD and has the same or similar folders as my 'C' drive, and I don't know why. From some searching this would appear to be normal and unavoidable, however, other people's 'F' disk only seems to take up a few hundred Mb's while mine has a capacity of nearly 20Gb.

Why is this file here, why are certain programs e.g. Movavi Video Suite defaulting to it for photo/video saves and can I get rid of it and return the 20Gb back to C or D disk?

Thanks,
Tom.

I believe I'm mistaken, this is part of my internal HDD, correct?

I don't know how it got there. When I installed W10 I formatted both my SSD and the HDD creating only two distinct partitions on the SSD for the OS and my games. The HDD was reformatted as it had XP on it, leaving it as one whole, contiguous drive and then copying all my files over to it from my back up drive, the HDD now solely being used for my slow stuff e.g. videos, photos, docs etc.

Somehow this extra drive/partition has appeared on the HDD.

I believe you are confusing formatting and partitioning, @Tommygunn. You likely only formatted the existing data partition on the HDD, and did not repartition the HDD to remove the previous Windows partition that was on it. If the HDD previously had a Windows installation with a separate partition (drive letter) for data on it, what did you use to delete the partitions on the HDD?

I believe you are right. After some further investigation it would appear that I overlooked the old XP partition and just went straight for the 'G' partition thinking I was wiping everything at once.
Thanks for the insight.

I've just received my new HDD this afternoon to replace the one in question, because it's old and tired. Currently formatting the new HDD so we'll see what happens but I'm sure everything will right itself.

Cheers,
Tom.

In Disk Management you can change what drive letters get assigned to which partitions and drives by right clicking on the partition or drive. Just don't change C: drive!

Ok, I've sorted this and did a proper format of the HDD and now it is just one single drive giving me the required three in total.

Thanks for the help,
Tom.
