When working with InfoPath, there are many scenarios where you may need to modify InfoPath XSN files. These include: fixing errors, changing web service urls, tweaking file names or SQL connection strings, removing/editing some value(s), etc. Thankfully, since InfoPath XSN files are just containers (cabinet or .cab files) of many other files, we can use built-in windows tools to break them open, make our changes, and then repackage them. This article explains the full process with an example.
