How do I upload multiple files into a folder?

I want something that allows me to upload a folder and when I add to the folder re-upload it, but only upload the new files.

• Answer:

  You could try Dropbox. You can install this program on up to three computers at a time, and as long as you make an account and login to your account before you install the program on each computer, it will have a record of all your files on every computer you put the program on. You can readily add folders to it and add files to each folder, and the files you upload will synchronize with the dropbox you have installed on each computer. It is free to download, and you get up to 2GB of space in your dropbox. You can get more space by recommending Dropbox to other people. There is also a premium account you can get that offers more storage space. I don't know if this is necessarily the type of program you are looking for. It is primarily a file-sharing program, although it is also a great place to store your multitudes of files and folders if you don't want them cluttering up your main hard drive. I use it for my SEO jobs, because the folders are organizable, and I have a backup on the family desktop computer in case my laptop ever crashes. Don't worry...if Dropbox crashes on your computer, you can still login to Dropbox.com on another computer and access your files and folders directly from the Internet.
