Now I saw one news about Copy and CudaDrive after my Dropbox take some space.
The news it's come from Copy and CudaDrive and will be closed.
This is the message from oficial website: copy.
Copy and CudaDrive services will be discontinued. We are announcing today that the Copy and CudaDrive services will be discontinued on May 1, 2016. Copy and CudaDrive have provided easy-to-use cloud file services and sharing functionality to millions of users the past 4+ years. However, as our business focus has shifted, we had to make the difficult decision to discontinue the Copy and CudaDrive services and allocate those resources elsewhere. For more information on this decision, please view the blog post from Rod Mathews our VP & GM, Storage Business.
