If you need cloud storage space, try Yandex. Disk for Android, it is a really good alternative to the solutions offered by Dropbox or Google Drive.
To start with, you can get up to 10 GB of space to store whatever you want by following four simple steps: create an account, install the app on your PC or Mac, download it and invite a friend.
Once done, it will be possible to send files from the sync folder that the tool creates on your computer or through the Yandex Disk online platform.
In addition to storing the documents you send, Yandex Disk can also play audios and videos and open edited documents in Office and PDF files. With it, you can access a lot of your stuff without having to download anything to strangers’ computers.
