Dired hd drives list

Dired hd drives list

[srdjan.markovich]

Hi

Is there a way to display list of hard drives, and available space on
them, in dired mode (something like df in linux) on Windows machines?

Thank you

Yes, download the Windows port of GNU df (it's part of the Coreutils
package and is available from the GnuWin32 project site).  It's a bit
buggy, but it does the job in most cases.

How would you incorporate the output from df into a dired listing?

Also, cygwin also has that program available as part of the cygwin
suite.

Why would one like it?  Dired already shows that output for the
filesystem where the listed directory lives, but I cannot figure out
why would I want to see other filesystems together with that?

I think it would be good - why not? 

It's what we have in Windows Explorer when My Computer is selected in the
folder tree. Saying that this would be useless for Dired is like saying that
it is useless for Windows Explorer. It gives you a top-level view of all
drives (and, in Windows Explorer, also some other things such as Control
Panel).

The Unix notion of root directory, /, only partly corresponds to the Windows
notion of individual drive root, e.g. c:\. In another sense, it could be
said to correspond to My Computer, that is, to a top level that includes all
drives. 

Dired has no equivalent of the My Computer level, I'd guess, because of its
Unix bias and legacy. That's OK as a historical explanation, but it doesn't
mean such a feature wouldn't be useful.

I have no objection to adding a special ``My Computer''
pseudo-directory in Dired, where all the filesystems would be shown.
But the OP wanted that as part of every directory, or at least that's
what I thought he wanted.

How useful would it be to those of us that use Unix?

Not useful at all. I thought that was clear. 

But how useful to Unix users is Emacs's use of a drive name
such as `c:'? Not useful at all - they don't even see it.
And they wouldn't see the equivalent of a My Computer level
in Dired, either - that would be for Windows users only,
just like `c:'.

There is not a simple one-to-one mapping between Windows's
file-system representation and Unix's, as I mentioned. In
one sense, the equivalent of the Unix root folder, for
Windows, is the My Computer level. In Dired on Unix you
already have such a top-level view. In Dired on Windows, you
do not. This is about adding that missing view.

One of the reasons I use Unix ;)

OT for Emacs: You can get such a listing in KDE, with its system:/
ioslave.

I don't see why not: `df' shows several filesystems on Unix as well.

Oh, OK, go for it. I was thinking of the My Computer level as, in a sense,
analogous to the Unix root directory. In Windows, going `up' from c: is a common
operation in Windows Explorer (though `cd ..' doesn't get you there, any more
than `cd ..' lets you go up from the root directory on Unix).

So sure, why not? That makes sense.

But `df' is not really analogous to Windows Explorer's My Computer level either.
`df' prints disk-space information no matter where you are, and it doesn't
change your location.

I was understanding the OP as suggesting that we add a `top' My Computer-like
pseudo directory to Dired, which you would get to, say, via `..' from c:, not a
command like `df' that leaves you where you are but prints info for all drives.
Dunno which the OP had in mind. 

Perhaps a command that just prints the info would be better in some ways,
instead of mimicking Windows Explorer by giving you a navigable place
(pseudo-directory) to view everything. The notion of current directory wouldn't
be problematic then. An advantage of the Windows Explorer-like approach is that
it does fit in with navigation, so you could do things like insert subdirs. The
`df' command approach would no doubt be easier to implement (nothing to do, for
Unix) and less problematic.

This is very essential thing. If I have printer, camera and usb
attached to my comp and if I want to copy (or save) file to USB flash
drive I must go to win eplorer and open My Computer directory to see
which drive is my USB flash and then go back to Emacs and type that
letter in the path...Silly, isn't it?

The question Eli raises is whether you need that info about
all drives in _each_ Dired directory listing. I don't hear
you saying "yes". 

I think what you are asking for is just to be able to go up
(`..') in Dired from some drive listing such as c: or d: to
the My Computer level, where you would see the space etc.
info for all drives - just as you do now in Windows
Explorer. Isn't that what you want?
