Installation instructions:

NHDPlusV2 data is distributed in compressed files created by 7-Zip (compression software) with a ".7z" extension. While 7-Zip can create files in standard Zip format, the NHDPlusV2 data is stored in a special 7-Zip format which creates even smaller compressed files. This helps preserve disk space and shorten download times.

7-Zip, and other zipping utilities that support ".7z" files, may be used to uncompress the NHDPlusV2 data. 7-Zip is a free utility available at: http://www.7-zip.org/download.html.
