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?
I use URL Opener to open the file in Firefox for Android. It works great. Copying via FTP or WEBDAV works, but not when Windows PC is connected to Android via USB.
