300035 - clearing cache should remove directory, not delete files

Status: RESOLVED DUPLICATE of bug 231300

(Core :: Networking: Cache, defect)

Description

[ratman]

clearing the disk cache, especially if set to the 50mb default, takes forever,
at least on windows machines.  this is particularly concerning after a crash,
because moz will freeze up while it slowly clears the cache after first starting
up after a crash (different bug altogether).

i believe that this is because moz deletes the cache file by file, using the
equivalent of the old dos "del"/"erase" command.  a much simpler and faster way
of clearing the cache would be to remove the cache *directory* altogether, and
then recreate the cache directory, rather than trying to delete the files
contained there.  this is what i usually do after a (non-moz related) crash to
prevent moz from freezing up when starting up again.  the delay experienced when
clearing the cache can be "replicated" by dropping into dos and clearing the
cache with the "del *.*" command.

okay, this isn't a very well-worded bug description, i apologize.  hopefully it
makes sense.

the only way to remove directories is by deleting all the files contained in
them and then the directory itself.

that said, the experienced delay was fixed in bug 231300

how do you do that, though?
