Windows Directory case not preserved

I'm using SyncBackPro to copy the whole of my F: drive to N:
My N: drive is on a disk enclosure I just installed, and before SyncBackPro started, it was completely empty.
The profile is still running, but it generated the following error:

Error: Failed to copy from Drobo V1 F: : Cannot create folder: N:\Backups\Apache2\HTDocs\Images\ (The system cannot find the path specified)

The input folder is F:\Backups\Apache2\Htdocs\images
The output folder (on disk) is N:\Backups\Apache2\HTDocs\Images

... so what path wasn't found (remember; the error message was compaining about a "path not found"...

What might have created the output folder with different capitalisation? As far as I know, it can only been SyncBackPro. So, why does the case differ?

What's more, SyncBackPro then seems to try to create folder N:\Backups\Apache2\Htdocs\images\ and gets an error, as it already exists. Windows cannot have two directories which differ only by case.

Then it puts out an error message that doesn't accurately describe the problem, as far as I can see.

I'm hoping that if I fixup the case of the directories under N:\ to match the ones under F:\ then I can run the profile again, without error. But it's a bit of a stab in the dark.
