It appears to be a support library for dfp.exe, which is the "Disk Footprint Tool". I never knew it existed until now, but it seems to be a potentially quite handy utility with a purpose similar to tools like WinDirStat (but CLI only?).

So to answer your question, no, it's not part of the telemetry infrastructure. And I'll add that calling that infrastructure "spyware" is a simplistic analysis of what's a complex issue. I say that as someone who goes to great pains to turn off as much telemetry as I can across almost all applications I use.
