I just found a relatively new cloud storage app called Copy. They are giving away 20GB (15Gb + 5GB for using the referral link) to new users. I'm a pretty avid Dropbox user so I always end up comparing things with them. So far I've been really pleased with Copy. There isn't anything it won't do that Dropbox does. I also think I may actually like their mobile app better than Dropbox's and you earn 5gb per referral without limit on referrals. Quote: Some great features: - 20GB OF FREE SPACE FOR LIFE! Thats way more than any of the other guys are offering in their free tiers. And this isn't temporary space like you'd get with other promos from Dropbox. - NO FILESIZE LIMITS. Some of the others I've tried (I'm looking at you Box) give you tons of free space but then cap you at 200mb or less file size limits. I uploaded a 1GB file as a test and it took it without complaints. - Multi-platform. They have a desktop sync app for Windows, Mac, and Linux and have Android and iOS mobile apps. - 5GB per referral you have sign up with no referrals limit! Compared to the others, I could only find 1 that gave 1GB free space per referral. (Note - it says on their website this is only going to be for a limited time so I imagine they will eventually lower it to 1GB or something) Enjoy your new free 20 Gb cloud storage! Have fun!
