I've run a full scan with dmde on the ntfs volume the share is on and then chose pure FS reconstruction and surprisingly a good chunk of what has to be recovered is there and the file sizes are reasonable (0.6-4mb for jpgs and pdfs and 15-1000kb for docx).
Once downloaded, you can simply extract the archive and launch the dmde.exe executable file. That's right! DMDE doesn't require installation because it's fully portable. That means you can download it to and launch it from an external storage device to avoid overwriting files on your main system drive.
Just a nit on the CPP option around the rotation code: CURVGRID is for when the dmde and dndx terms are nonzero and require the extra advection terms to be computed. It is not a flag for whether your grid is aligned north-south and east-west. In fact, north-south grids generally have nonzero dmde on a sphere.
