last year I blogged about building an InfoPath files from before extracted manifest file (http://developers.de/blogs/holger_vetter/archive/2015/07/16/cabfilepacker-for-creating-infopath-cab-files.aspx).
But there is a different and easier way to repack the extracted .xsn file.
Just open the manifest.xsf file with InfoPath Designer, click “Save as” and then pick “.xsn file”. This will save your form as a packed InfoPath file.
No need to use tools for packing files into a .cab file.
