I dont know if this is your issue but the extract command only works on packages that have been compressed using TEM from memory. When I use SWD, I can zip an entire folder to deploy and then use the extract command to unbundle. This command however did not work when I included my own zip package. For that you would probably need to use an OS level Extract command versus the relevance extract command
The target directory shouldn’t contain a slash at the end.
The archive must be made by BFArchive
Also make sure that the path you are extracting to doesn’t force the path length to go over the maximum number of characters in a path (260 characters) for a non UNICODE application
