I am running Mavericks and am really not interested in updating to Yosemite. However, I am a grad student and have thousands of pdfs I would like to upload to my iCloud drive (200 gb storage plan) so I can read them on my iPad via GoodReader. Literally thousands of pdfs. I tried uploading via iCloud.com but in two hours only two documents uploaded. That will not do. I know if I updated to Yosemite I would have an iCloud drive right in Finder and (probably) simply be able to transfer files (with multiple folders) directly into that drive. However, I really love Mavericks and don't want to do that. So, how do I get these thousands of files into my iCloud Drive without updating OS X? Thanks in advance.
