.ISO compressed to .7z

[Andrie]

Question: Why don't you archive the .iso images to .7z so they are smaller?
Reason: I don't have so much data so the download should be smaller!
Consequence: I can't download Linux Mint because the .iso is to big.

Have you tried this before suggesting it? I was able to compress the linuxmint-14.1-cinnamon-dvd-64bit.iso file by 0,68% with 7z (reduced from 881 MiB to 875 MiB, or a 6 MiB reduction). That doesn't seem very significant.

Also, it would mean that anybody downloading the ISO would need to be able to extract .7z files. I'm not sure that Windows is able to extract such files, or OS X, or for that matter Linux distros that don't have p7zip installed. Extract such a huge file is slow, and would mean that instead of 881 MiB disk space for the ISO file, you would need almost double that because you can't delete the .7z file until you have extract the archived ISO file from it...

I'd recommend instead you use either OSDisc.com or On-Disk.com to get Linux Mint on DVD or USB stick. Both are Linux Mint partners, and contribute a portion of their sales back to the Linux Mint project. So you'd be supporting the project as well! And you can share the DVD or USB stick with others in your area that want Linux Mint but don't have a broadband or unlimited data subscription.

p7zip is not the original http://7-zip.org/.
and there'e a difference between compressing and archiving!

I don't follow; that website only has Windows binaries. How would the Linux Mint developers use those?

p7zip package description says:

Code: Select all

Description-en: 7z file archiver with high compression ratio
 p7zip is the Unix command-line port of 7-Zip, a file archiver that
 archives with high compression ratios.
 .
 p7zip provides:
  - /usr/bin/7zr
    a standalone minimal version of the 7-zip tool that only handles
    7z archives. 7z compression is 30-50% better than ZIP compression.
  - /usr/bin/p7zip
    a gzip-like wrapper around 7zr.
 .
 p7zip can be used with popular compression interfaces (such as File
 Roller or Nautilus).
 .
 p7zip-full provides 7z and 7za which support more compression formats.

Doesn't sound like it will be inferior to your Windows program. What compression ratio were you able to achieve?

Are you kidding me? Go do your research first before making a fool of yourself (this is the second time you've made a fool of yourself).
Now, you should either not reply at all, or make an answer that actually makes sense.

http://p7zip.sourceforge.net/
p7zip is a port of 7za.exe for POSIX systems like Unix (Linux, Solaris, OpenBSD, FreeBSD, Cygwin, AIX, ...), MacOS X and also for BeOS and Amiga.
7za.exe is the command line version of 7-zip, see http://www.7-zip.org/.
7-Zip is a file archiver with highest compression ratio.
