Problem backing up downloads folder

Question

I upgraded my hard drive to an SSD drive earlier this year and apparently I never set up the backup for the downloads, documents and desktop. I just went to do so and when I click setup I get an error message on the downloads folder saying that Dropbox and the downloads folder are on different drives. I went to my drive manager and noticed that I have a C drive with 450 GB and a D drive with about 1.8 TB and the Dropbox folder that is being synced is on the D drive but I also discovered that there's a Dropbox folder on my C drive under users/"username". I think what happened was when I first reinstalled Dropbox It tried to set up the folder on the C drive where it was supposed to but ran out of room and I don't know how the D drive got created but that's where Dropbox folder is now located and being synced. I need to figure out how to fix this.

I've adjusted my sync settings so that I have only just under 300 gigs being synced to the Dropbox folder on the D drive and I have about 387 gigs available space on the C drive so I could move the Dropbox folder back to where it belongs but then I still have the problem of available storage space. It's a 2 TB hard drive and I don't know how it got set up with 450 allocated to the C drive and the rest to the D drive. If I move Dropbox back to C there won't be enough space to sync the rest of my stuff that I had on there before.

So one question I have is if I move the Dropbox folder back to the C drive, would I be able to somehow add more storage to the C drive without having to reformat things or how do I go about setting this up so I can back up my downloads folder. That's really the main issue here is being able to back up the downloads folder just in case something happens.

I also have an issue where apparently my desktop and documents are connected to OneDrive so Dropbox says it can't back up both but let's figure out one problem at a time. Hopefully all of that makes sense.

Yes, in order to setup the computer backup, both the Dropbox folder and the Documents, Downloads, Desktop folders would need to be on the C drive. They'd also need to remain there permanently.

Moving the Dropbox folder back to the C drive isn't the issue, since it can be done in the desktop app settings, although it sounds like you'd experience issues in the future with the space on that drive in general (since there isn't much space left on that disk afterwards).

So moving the downloads and desktop folders to the 😧 drive where the Dropbox folder is currently loicated wouldn't work? They would then be on the same drive.

This is what I found for moving the downloads folder and would be the same for the desktop folder, then they would be on the same drive as DB.

Thanks for the info. If you do plan on using computer backup, the Dropbox folder would need to remain on the C drive, so you won't be able to move it to another drive, either internal or external.
