Machine: Win10 VR Beasty, Has a 12TB+ drive pool as well as a M.2 boot. Mistake: Switching Filehistory on for Windows 10, and letting it use drive pool. Problem: I run out of space on the drive pool and turns out that FileHistory has used a few terabytes of data. Fix: Using command line to delete everything is still taking an age, there's still over 5.5million files to delete Question: Other than some method that involves moving the 'I want to keep the data' off the pool, and deleting the whole thing is there any way I can quickly delete a 1TB+ folder that contains tens of thousands of nested folders and millions of files? At it stands at the moment I'm going to have to put the delete into a startup batch and get it to chip away at the files bit by bit. rmdir seems to be the quickest, but on a slow drive pool with this much data it's still silly slow. Quicker than not using cmd, doing it via the desktop would have taken over 1,500 years.
