Why doesn't the batch file output the tree to a file?

Question

cmd/bat

There is a task - to create a batch file that creates a folder, and in it - a file with a directory tree and the current date. The batch file does everything except the directory tree. What am I writing wrong?
MD C:\User6
echo Start
echo tree%C:\tp70%> C:\User6\test.txt
echo %date:~-8%>C:\User6\test.txt
echo Stop

Before , otherwise the file will be output just the line treeafter . In the next command, instead of , it is necessary that the file be appended, and not overwritten. echoecho>>>
