What is an XSN file?
Form template used by Microsoft InfoPath, a form design and creation program; saved as a compressed .CAB (cabinet) file, which contains multiple files.
XSN files include a schema (.XSD) file, an .XSL style sheet, .JS or .VBS script files, and image files used by the form interface. Individual files can be extracted from XSN files by choosing within InfoPath.
