I have a rather large (~500GB) 7-zip archive. I originally made it when I had more space available, and did so at rather fast, low-compression settings.
Now things are tight, and I'd like to try and compress it down even more. However, I lack the free space to decompress and recompress it. (That's kinda the problem to begin with).
Is there any way I can recompress it inline? Of course, I could easily do this with a
.tgz archive on Linux using streams, and I'm hoping there's something similar.
I'm using 7z because I'm normally on Windows, but I can use either Linux or Windows for this specific job.
