WinUtils

Small utility commands to improve the poor standard Windows command line cmd (PowerShell probably does better).

---

sleep

Add sleep functionality to Windows standard shell (can't believe they didn't do it!)

sleep 1         (sleeps 1 second)
sleep /ms 500   (sleeps half a second)

mcopy

Allows copy resume of partially-copied file. Very handy when you have to transfer big files over a poor network connection. Currently handles only one file (standard copy command works fine for multiple files).

/y will overwrite destination if it already exists. /c will continue copy at the end of destination, after checking that the last 8KB are the same.

mcopy [/y] [/c] source destination

niceio

Allows changing disk I/O priority, from Very Low (0), Low (1) or Normal (2).

niceio <PID> [0|1|2]

If "priority" is not given, current priority will be printed. N.B. that it uses unofficial, undocumented Windows API that might change in later version (but it's working on my Windows 10 laptop :)).

While you cannot boost a specific PID, you can lower the priorities of other disk-hungry PIDs.
