Solved: Merging multiple files in multiple sub-folders into a single folder tree

I have several folder trees each containing many sub-folders, say A, B, C, D and so on. The names of the sub-folders are mostly the same between the various folder trees, although there could be an X, Y, Z in one folder tree and not in others, or only 20 sub-folders in one folder tree and 40 in another.

Each sub-folder contains many files, most of which are the same as those in other sub-folders of the same name. For example, folder A in one tree may have 50 files, 40 of which are the same as sub-folder A located in another folder tree.

What I am trying to achieve is a single 'master' folder tree containing all of the sub-folders in each of the existing folder trees, each sub-folder containing all of the files in all of the sub-folders of that name, without any sub-folders or files in each sub-folder duplicated.

I can achieve exactly this by manually moving files to the corresponding sub-folder in the 'master' folder tree, clicking 'move and replace' and ticking 'do this for the next x conflicts', but it is tedious and very time consuming.

Thank you in anticipation that someone will know how to automate this otherwise laborious process.
