Hey @amin.khormaei
with the files from the tutorial you can put different folders inside
\ContentPack\Samples\MyContentPack\Content
because inside the config.ini we use
[AdditionalFilesToAdd]
+Files=Samples/MyContentPack/Content/*.*
So it packs everything inside that folder. This way you would have multiple folders inside ONE feature pack.
If you want different feature packs for each of the different folders you could copy the tutorial files, extract/migrate your content and change the name inside the *.json file and inside the *.bat file.
