Q. How can I make smaller .zip archives?
A. Use 7-Zip to make your .zip archives using some command line options.
Assuming you have installed 7-Zip in c:\Program Files\7-zip\7z.exe
Make a batch file that does:
"c:\Program Files\7-zip\7z.exe" a -mm=Deflate -mx=9 -r myzip.zip myfolder/*
Explanation of options:
a Make an archive
-mm=Deflate Be compatible with .zip
-mx=9 Slowest with best compression
-r Recursive. Add all folders inside folder
myzip.zip The output archive
myfolder/* All files and folders inside myfolder. Do NOT use *.*
There are other options that might make it slightly smaller but I prefer to just let -mx=9 (ultra) do it.
