Nothing in your description sounds difficult to do in powershell. You can certainly output "many-things" from a part of the pipeline that takes "single-things" as input. Crawling files is a single command, then you can do whatever you want with each one in the next part of the pipeline - "map" from file info object to something else (e.g. custom object with filename, size, checksum, etc props) 1-1, multiplex each file into N output objects, buffer file inputs until some heuristic is met then emit outputs, etc.
