I'm trying to download a large number of files that all share a common string ('DEM') from an ftp sever. These files are nested inside multiple directories. For example, 'Adair>DEM*' and 'Adams>DEM*'
The FTP sever is located here:ftp://ftp.igsb.uiowa.edu/gis_library/counties/ and requires no username and password. So, I'd like to go through each county and download the files containing the string 'DEM'
I've read many questions here on stack and the documentation from python, but cannot figure out how to use ftplib.FTP() to get into the site without a username and password (which is not required), and I can't figure out how to grep or use glob.glob inside of ftplib or urllib.
Thanks in advance for your help
