FTP Downloads
If I have agreed to provide you access to a large dataset or file:

Have the user name and pasword I provided at hand and open your FTP client software (e.g., FileZilla).

If you are using FileZilla:

At the top of the screen, enter Host: ftp.jim-bland.com, Username: [the one I've proveded], Password [the one I've provided], Port: [leave blank].

In the "Local site" panel on the left, navigate to the folder you want to download to.

In the "Remote site" panel on the right, files available to you should be displayed. Right click on the desired file and click Download.
