I want to add files from a file list in a subfolder inside an existing .zip file 7z a -tzip -mx=0 test @add_files.txt Maybe in add_files.txt I can add lines like this? -si"parent_folder\subfolder_level1\subfolder_level2\file 1.ext" < "C:\users\username\Downloads\file 1.ext" ??? How do I add multiple files instead of single file with single -si switch ?

How can I use this new method ?

So then, do I need to add zip extension base_archive.zip when using -tzip or not ?

even with -tzip enabled, 7zip gets confused if extension isn't there? 7a a -tzip C:\....\....\base_archive and without -tzip 7a a C:\....\....\base_archive.zip ??

15 GB of onedrive storage is what I meant. Im using a network folder mounted with onedrive though..
