Moving Files from a Shared Drive to a SharePoint site

Hi,

I've seen the moving of files from a Shared Drive to a SharePoint site can be tricky, depending on the size of the files that are to be moved.

What is the best and most effective way to move folder, files.
I'm not sure yet of the number of folders and size of the files that will need to be moved?

Can anyone provide an advise on this, please..

Regards

Chris
