you will get a prompt allowing you to sel ect if you want to replace or skip the files
I only want to replace the older files with a newer one. If I choose "replace all" it's not clear to me whether identical files are going to be uploaded all over again, or not. If I sel ect 1GB of data files to transfer (assume each data file is 5MB in size), but only 10MB is different fr om what I have transferred before, will "replace all" use up 1GB of data, or 10MB? Please advise.
