Is unzipping multiple files in WTX really as awkward as I found it to be? At the command line, the code is something like "unzip zipfile.zip" and the zipped files are unzipped. In order to do this in WTX, I first created a type tree to read a zip file. Then in the map output card, I have three functional maps. The first FM extracts the zipped file names, the second FM GETs each of the zipped files using the ZIP adapter based on the file names from Step 1. The third FM then PUTs each of the unzipped files from Step 2 using the file names from Step 1.

Have I made this way too complicated? What have I missed?

The manual says

Archive Restore
Use the Archive Restore command to retrieve files from a specified archive. You
must specify the following arguments with no preceding adapter command:
archive_name,files_to_unzip
Option Description
archive_name Specify the name of the archive that contains the
files to be restored.
, The comma is a required separator between
options.
files_to_unzip Specify the files to be restored from archive.

Data Sources
The following is the syntax of the Archive (Zip) adapter commands used for data
sources:
archive_name,files_to_unzip
Unfortunately there are no examples to show how to use it. I've only used it to create zip files.

How about using an output card to run the batch script to do the unzip?
I tried using the adapter and it seems you need to know the name for the file you want to unzip. Your typetree for the zip file must be interesting.

Yes, your method would work. I could also model the economy of the world from a WTX map if I call the right external program. It is trivial to extract zip files in a script. My point is that I didn't find an easy way to do it from within a map. Not saying it can't be done. I just didn't find any method.

I just wanted the file names from the zip file so the type tree is rather simple with ugly record terminators. They're actually initiators in the zipfile but I found it necessary to define them as terminators in the Type Designer.

Our unzip maps use text blobs. The problem with unzip in TX is that you need to know what files are in the zipped file. So, if you don't have a reference and have multiple files it gets difficult fast or you can use the bat file.

Our standard is one file per archive. Archive file name contains the zipped file name.

Has limitations as well but for internal use its easy to inforce.
