Tips for Downloading from the GIS Hub Data Portal
Data can be downloaded from the GIS Hub Data Portal beginning with one of two methods: Browsing through the data themes or by searching for the data. If searching, simply enter a search term (e.g., fire) in the search box and then either wait for a moment to see items appear below the search box or press <enter> to see a full listing. See the image for a basic overview of the downloading process.

Tips for Downloading Files from HTTP
Download File Manager
You may wish to consider using a file download manager to help ensure complete downloading of files should the download connection be interrupted. One such tool is the Free Download Manager, which is not endorsed nor supported by the GIS Hub but is listed as an example.
Download Multiple Files
To download multiple files at a time you may wish to consider using a utility such as wget. After installing wget, an example for downloading all files from an HTTP directory from within a command prompt is:
C:\data> "c:\Program Files\GnuWin32\bin\wget.exe" -rv

An example of downloading only the .xml files is:
C:\data> "c:\Program Files\GnuWin32\bin\wget.exe" -rv -A.xml
