Yes it's correct that you need two maps and you have to know the names of the zipped files.
Solution:
We have written an universal unzip map by creating a map that reads the zip file (zip analyse map).
The content of all zip files is standard (always the same structure - in the web you can find a description of this structure) so that you can do this.
The result of this first map is a list of all zipped files (name, size,....)
This result is passed to the unzip map via ECHOIN function.
