Automating Disk Cleanup on Windows using commandline

Question

I am trying to run Disk Cleanup in the Command Prompt (and through a C# program) and so I went through all the available options from this link:

Whilst I am just trying to understand what I can do, it would be good if someone could explain why the drive option /d cannot be set while specifying /sagerun:n.

Or is it possible, by some way, to run /sagerun for a specific drive?

Answer 1

You have to use /d with /sageset:n; /sagerun:n just runs the configuration as set in the registry key.

In other words, you can't create a set of cleanup options and then run them on individual drives, you have to set cleanup options for each drive. If you run /sageset:n without the /d switch then it is supposed to run on all drives when you use /sagerun:n.
