It would be very practical in Finder to be able to quick look at archived files, without uncompressing them. Even better, to be able to only extract the files we need, instead of the whole archive.
There are already solutions, e.g.:
Treating archives as folder would be nice IMHO.
I know, I know. But its another (relatively expensive) application to buy.
I havent tried it, but the link I posted says, the plugin can be used for free.
Marc’s right – it’s free.
