Good day Vaclav,
VJ> 7zip module for rar handling is under the same non-free license
VJ> as the original unrar utility and are based on the same code (and
for example
VJ> in Debian, there is a separate package p7zip-rar, which is under
non-free
VJ> section), so there is no advantage in using p7zip for viewing rar
archives.
Sorry, I had to investigate this question in first place.
VJ> If you prefer opensource unrar, there is some available in Debian,
which has
VJ> the same syntax and name as the non-free unrar, but this does not
handle all
VJ> versions of rar archives.
I see, the rarsoft site offers free unrar utility, so inspite of
proprietary archive format it is not hurt to use the programm.
VJ> If you want to change the program, that Krusader uses to process
archive, use
VJ> Settings->Configure Krusader->Dependencies->Packers, but the
change works
VJ> only if the program you specify there has the same parameters as
the default
VJ> one, which is probably not the case of p7zip and unrar (only if
you had
VJ> written some wrapper, but I personally see no point in doing so).
So, the programms listed there are standard in some sense and krusader
assumes that they have certain options.
Well, thanks for your time and description.
