NexusBV release 0.7 stored in a 7.02 MB zip file, filed in the BIOS and firmware category. The only details carried by the name are the program title and version; BV is the usual shorthand for boardview, so this is likely a viewer for PCB layout files. Such tools help when tracing a signal between components, finding pins on a net and comparing diode-mode readings with a known-good reference. Inspect the extracted files first and verify compatibility with the boardview formats you intend to open.
