how to move files in background with dired?

[Joakim Verona]

Is there some way to manage a background transfer queue for dired?

Maybe its easier to understand what I mean if I explain how I would
like it to work:

- I mark a number of large files to be moved to another disk, which
  takes time. 

- dired puts the moves on a queue, and makes a "progress buffer"
  showing how far each move or copy has progressed. (this would look
  something like wget.el:s progress buffer)

- each move or copy is done in the background with cp or mv shell
  commands, so emacs is not locked

- Im now free to add more moves or copys to the queue by direding some
  other directory

Ideally the same interface would be used for remote operations, with
tramp or something.

Sounds doable. Has it been done?

You might be able to use dired-do-shell-command ( '!' in dired-mode ).
Looks like you can even do it on groups of files... you could make it
queue by using the * or do all operations concurrently using '?' (look
at the docs for dired-do-shell-command).

After hitting '!' on the file of interest I entered 'cp ? c:/temp &'
and it worked just fine. Not sure how well it would work with tramp
though since my guess is it just uses the relative path of the file and
not the abosulte path.

Probably no ? i guess, as elisp doesn't support multithread.

Doesn't really have anything to do with multi-threading... these
commands launch sub-processes.

Emacs does support a notion of a process sentinal... you could probably
fairly easily set up one of these up to do what Joakim requested if my
above suggestion does not solve the problem for him (i.e it does it
concurrently rather than queuing them).
