Multiple DxO Folders in Appdata and Programdata

After a very long history with the DxO products, I have the following folders spread over my system disk (I have not upgraded to DPL 6, FP 6 and VP 4 yet) :

C:\Users<…>\AppData\Local\DxO\Analog Efex Pro 3
C:\Users<…>\AppData\Local\DxO\Color Efex Pro 5
C:\Users<…>\AppData\Local\DxO\Dfine 2
C:\Users<…>\AppData\Local\DxO\DxO PhotoLab 5
C:\Users<…>\AppData\Local\DxO\HDR Efex Pro 2
C:\Users<…>\AppData\Local\DxO\Nik Collection

C:\Users<…>\AppData\Roaming\DxO\Nik Collection
C:\Users<…>\AppData\Roaming\DxO\DxO PhotoLab 5

C:\ProgramData\DxO\DxO PhotoLab 5
C:\ProgramData\DxO\HDR Efex Pro 2
C:\ProgramData\DxO\Nik Collection
C:\ProgramData\DxO\Sharpener Pro 3
C:\ProgramData\DxO\Analog Efex Pro 2
C:\ProgramData\DxO\Color Efex Pro 4
C:\ProgramData\DxO\Dfine 2
C:\ProgramData\DxO Labs\Licenses
C:\ProgramData\DxO Labs\Data

This is obviously too much. Could these folders be organized more consistently, please ?

The files in these folders are generally not older than one year. So, I guess they are not leftovers from previous versions. I do understand the differences between Programdata and the user’s Appdata but there’s apparently much room for optimization.
