The files database.* are NV2 database files. The files datad.nv, datac.nv, datae.nv, and datap.nv are NV1 files (datad.nv is the NV1 books). NVCOPY belongs to NV1 (backup and restore program). The NV1_NV2 files where created when running NVEXPORT from NV1. These files are used when running NV1 Import from the NewViews 2.0 menu.
