When you create your own site, you will have at least two locations: your local PC at home (local) and a site in the net, where we all find you (remote)! So you need to somehow connect your local computer with your remote site, when you want to show us all the nice pics you’ve made and upload them to your (we)blog or website. That is what you need an FTP client for and you may well think of it as some sort of a file manager.

If you only want to facilitate your downloads, you will be well served with a download manager, a piece of software that enhances downloads in many ways.
