Mega — the cloud storage, developed by Kim Dotcomm and sharpened for maximum safety of user data. The client provides the cloud access (users will receive 50 GB of space for free and forever, we will have to pay), allows you to view downloaded files, and if you do not find what you need — you can use the search, move files into folders, delete, and rename; download documents to your device, share with friends (generated download link), add the new files. It is particularly convenient that you can attach the photos from the camera. And in addition to the protected account tied to the mailbox.
