I have created a .url file using Windows Explorer on a Windows 10 computer. When I try to copy the .url file to my Samsung Galaxy A5 phone the file cannot be copied to my phone. I just hear a strange sound, which is either SystemSound.Asterisk or SystemSound.Exclamation. I cannot tell the difference between these two sounds. What causes that I am not able to copy the .url file and why does the sound sound (as specified above) instead?
