cd . > empty2.txt
Third, use the call command.
call > empty3.txt
fourth way using the copy command
copy > empty4.txt
The fifth way, using the echo command.
echo . > empty5.txt
The sixth way is using Notepad on windows
notepad empty6.txt
This creates empty6.txt and opens the empty file in Notepad.
The seventh way is using the break command.
break > empty.txt
