hi Gregory,

i've gone down that road with make-temp-file until i realized that i
cannot trust that the temporary-file-directory (usually /tmp/ in linux)
has enough space to allow such action (e.g. it might be a small
ramdisk).
But in your example i see you create the temporary dir in the current
one where the archive also resides, correct?

and i just realized that this is possible in elisp:

(let ((temporary-file-directory "/home/mvar/"))
  (make-temp-file "boing-" t))

without altering the global var. I think this is quite feasible and will
give it a try, thank you!
