Advanced GIS Practice Exam Prep: Practice Test & Study Guide

When you unpack a layer package, the contents may not appear in your current workspace primarily if they were unpacked to a location different from where you're currently looking. This situation often arises if the unpacking process does not automatically direct the files to your active directory or workspace in ArcGIS. Therefore, checking the specified unpacking location or searching through your file system can help you locate the files.

While the other choices might seem relevant, they do not accurately address the situation. For example, a layer package typically does not need conversion into shapefiles to view its contents, and refreshing or unzipping processes are more about ensuring visibility or integrity rather than the actual location issue of unpacked files.
