Things are getting complicated.

How can one add a directory, a file, ... to an archive ?

1) If the archive is compressed (.tar.gz), tar says
"Cannot update compressed archives".
Ok, I return KIO_ERROR_NotPossible.

2) For a normal tar archive (which is less useful than tar.gz, I want you
to note), adding something needs a temporary directory hierarchy in order
to create the files :
Try it on command line, it's really hard ;


-zsh- dfaure 11:17 /tmp>mkdir parent
-zsh- dfaure 11:20 /tmp>touch parent/afile.txt
-zsh- dfaure 11:20 /tmp>tar cvf myarchive.tar parent/
parent/
parent/afile.txt
-zsh- dfaure 11:20 /tmp>rm -rf parent

ok, I have a tar archive.

-zsh- dfaure 11:20 /tmp>tar rvf myarchive.tar parent/child/
tar: Cannot add file parent/child: No such file or directory
tar: Error exit delayed from previous errors

I can't add something to it if it doesn't exist in a local subdir first.

-zsh- dfaure 11:21 /tmp>mkdir parent/child/
mkdir: cannot make directory `parent/child/': No such file or directory

I can't create it easily. The whole hierarchy is needed.

-zsh- dfaure 11:21 /tmp>mkdir parent ; mkdir parent/child/
-zsh- dfaure 11:21 /tmp>tar rvf myarchive.tar parent/child/
parent/child/

That's it, it worked.

Now, is kfm supposed to do all this ???

I think I'll let Mkdir return 'not implemented' as it already did !
Grrrr, lost 2 hours for nothing.
