!!!Pack and unpack in 7z format with a Mac
First open the Terminal app and type in:\\
\\
brew install p7zip\\
\\
The program itself is called: '7z'\\
\\
In Terminal you can type in:\\
\\
man 7z\\
\\
for further information about the program. Please type 'q' to quit the help menu and return to Terminal.\\
\\
For a smart handling, please type in:\\
\\
cd <path of the folder, you want to work with>\\
\\
for example:\\
\\
cd folder\\
\\
Even more smart is to just type in 'cd ' (please don't forget the blank after the letter d and then just drag & drop the folder with the archive inside the Terminal window to the actual cursor position! That saves you a lot of typing! :-)\\

!!Example for packing
For packing a file or an archive, please type in:\\
\\
7z a file.7z <path of the file>\\
\\
file.7z is the name of the archive which will be created in 7z format with the suffix 7z.\\
\\
<path of the file> must be the path on your Mac leading to the file and the file itself at the end, of course. The same is true when dealing with a folder.

!!Example for unpacking
For unpacking a file or an archive, please type in:\\
\\
7z x <path of the archive.7z>\\
\\
The program will then unpack the file 'archive.7z' in the same folder.
