Ordering of files

I have a folder of mp3 files that I am trying to arrange in a particular order to create a favorite playlist. I have prefixed the mp3 filenames with numerics followed by alphabets. In Windows explorer, i could freely drag a file to any position I want and have it stay in this order until I want to sort it back into numerical order by just clicking the name header. In Directory Opus, I cannot move the files to a particular position within the folder as they seem stuck in numerical order. I tried most of the folder options even unticking the box in Folder Options->Display set to "Numeric order filename sorting. Even after unticking this box, I still cannot move the files freely to the postion I want to test them out in, within the folder listing. Can someone please advise me how I can do this?

On another note, in Windows Explorer, I often have three Windows opened, to cut and paste files as the three-window-view allows me to have a better feel of what's there and what's not in three different folders. Is there any way to open three windows in Directory Opus without having to open another instance of Directory Opus?

Thank you

Arbitrary sorting is not possible at the moment, but you could do it easily in any playlist editor.

Windows Explorer doesn't support arbitrary sorting either, not for many years.

In Opus, the files have to be sorted by some criteria. You can use file descriptions or similar to, indirectly, make files sort in an arbitrary order but there is no direct way to drag files into different orders. Explorer has been exactly the same, since Windows Vista I think (and definitely since Windows 7).

You can open as many Opus windows as you like. There is only ever one instance of Opus (i.e. only one dopus.exe in Task Manager).

I don't know if what I've been doing is called arbitrary sorting but I've posted an image here of what I mean. It's okay if it's not possible in Directory Opus...

Turns out it was removed in Win7 rather than Vista: sevenforums.com/general-disc ... lorer.html

It's never been supported in Opus.
