Sort all files in a partition by size

Sorry if this has already been asked, but I did a forum search and didn't find a question like this ...

I want to be able to get a list of ALL the files in a partition, including hidden and system files, and then be able to sort that list by filesize, largets being at the top.

I know how to do this for individual folders, but I want to be able to do this for an entire partition.

Is there any way to do this simply? I'm using DirOpus 10.5.2.0. 32-bit.

Either Flat View or Find would be the normal way to do this - but whatever method you already have that works for a folder should also work for a drive letter as well.

Thanks very much -- didn't know about Flat View.
