Yandex Disk
Yandex.Disk () is a cloud service created by Yandex that lets users store files on “cloud” servers and share them with others online. The service is based on syncing data between different devices. Yandex.Disk was launched in English in June 2012.

Features 
Storage — users can upload and save files. There are no restrictions on the length of time files can be stored. All files are uploaded over an encrypted connection and are checked by an antivirus.

Syncing — files are synced between all the user's internet-enabled devices either through the web interface or the Yandex.Disk mobile/desktop application.

Sharing — users can share file download links with others.

Preview — the built-in flash player lets people preview songs.

Integration with other Yandex services — lets people manage their files on other Yandex services such as Yandex.Mail and Yandex.Narod. All sent and received mail attachments are automatically placed in one folder and can easily be searched.

WebDAV support — means that files can be managed with any application supporting the WebDAV protocol. The Yandex.Disk API can be used in any software program supporting WebDAV.

Since October 18, 2019, Yandex.Disk has started throttling WebDAV, causing some clients to time out, the official page redirects to the Yandex.Disk 3.0 client page, support writes: 
“Yandex.Disk is a personal service that is not designed to be used as an infrastructure element. For such tasks, we have Yandex.Cloud"
