Uploading / downloading entire file structures

Hello all!

Curious question here....... One issue that I have trouble with is uploading entire dirs and sub dirs in one stroke. For example, when i have a file structure with one folder that includes fiels in subfolders and so on, I can seem to upload the inner subfolders and their contents in one upload. The same goes with downloading. I have to keep creating new folders to get the structure right. Any advice?

Thanks so much -Jay!
