I need to upload thousands of pdfs (I have 200 gb plan) to my iCloud Drive. Attempting to do so via iCloud.com resulted in about one file per hour rate. In the old days on could simply transfer via iDisk. I know if I updated to Yosemite I could do the same via Finder in an iCloud Drive drive. However, I don't want to update to Yosemite. So, since iCloud.com isn't working out how do I get these thousands of pdfs (grad student) to iCloud so I can have access to them on my iPad via GoodReader?
