Question:
Is it possible not to physically copy the files that we want to synchronize with the clouds to the clouds folder on the PC?
PS: For example, is it possible to add links to files (or the like) that we want to synchronize in a folder of a specific cloud?
PPS: the question is interesting, so as not to multiply files in folders of several clouds on a PC, tk. there is a duplication of the same files if you want to save the files in Mil.cloud and Yandex.Disk.

Answer 1

symlink worked fine for mail.ru
unfortunately I don't know how to do it under win

Answer 2

Attach the Yandex cloud folder to the mail folder.
I don't think clients will understand symbolic links. But try.
