How to keep access to your files?
Just transfer the files you need to the cloud. What is a cloud? Nothing complicated — this is a repository of information (your files, documents, photos), which is located where it is not known, but you can access it from anywhere in the world via the Internet.
There are several similar services, but for tablets and smartphones the most suitable cloud is Google Drive. Each user is given to store 15 GB of information for free, and access to your files will be possible from any device — computer, smartphone, tablet, etc … Only you and no one else controls access to information on Google Drive.
