Yes, I did hit this button. Major fail! Now I remember that there was a button. I just hit it, barley reading it. Whats the text on it? “Override Changes” ?
I expected B is now allowed to overwrite A, but this was not the case. Or does it mean, that A now has the permission to overwrite all files on B? For a non native speaker this is highly unclear.
The button “Override Changes” is only displayed, when the folder is “send only” and another device send changes to this device. Clicking that button will override the changes received by other devices. If that changes were new files, that files will be deleted.
I’ll admit that even when I repeatedly read the documentation I’m unable to remember the effect when I see that button, so I have to carefully look at the documentation again - every time.
