How do I enumerate available drives.

I need to eumerate all available drives in a C# Windows Form application (
and then of course the directory tree, but that's not the problem)

My question is, how to I enumerate all the available drives?
My initial thought was along the lines of

DirectoryInfo di = new DirectoryInfo( "c:\\");
DirectoryInfo Root = new DirectoryInfo( di.Parent.Name. ToString() );
DirectoryInfo[] RootDrives = Root.GetDirecto ries();

This, of course, doesn't work as the parent of c:\ is null.

For my immediate needs, I could simply loop through a:\, b:\, c:\... z:\,
test to see if the new DirectoryInfo(" x:\\") threw an error, and be
satisfied with that.
This seems, at least, to be crude. I also would like the ability to get UNC
shares.

Anyone have a solution?

Thanks
Phil

Hi Phillip,

To enumerate the drives you can use...

System.IO.Direc tory.GetLogical Drives();

yes, that's the simple question: is there some python standard or 'Python for Windows Extensions' functionality to iterate or list-return the available drives ('A:', 'B:', 'C:', ...) on a machine running windows? Thx in advance.

I'm trying to make a tree list of possible storage devices for a small app but I have no idea how to get them. I want something very similar to windows explorer's tree view. Do I have to manually work with each one(hard drives, USB drives, networks, etc, special locations, etc..) or is there some way to get all these possibilities enumerated for me? Thanks, Jon

Hello, I've been trying to find a way to enumerate all drives- logical and virtual starting at the desktop for an explorer clone. I know how to get the logical drives and icons, but have not found a way to get all the drives and folders. I think IShellFolder with enumobjects is used but I can't find an example.
