If the files are located in the Yandex.Drive folder and are marked with the icon in the program, but they don't appear on other computers or in the web interface, please let us know by using the form at the bottom of the page.

Shorten the file names in the Yandex Disk folder. Check if the program has stable access to the network (antivirus apps and firewalls might block the connection).

The synchronization speed is designed to conserve bandwidth and system resources. The synchronization speed may also be limited by your provider. Please check your internet connection speed.

If you want to delete a file from your computer, but save it on the server, follow the instructions to set up Custom folder syncing.
