cmd append to file > extra space in the end

Question

set NUMBER=0

echo 3.3.3.%NUMBER% > "file.txt"

after running this command the content of file.txt is 3.3.3.0 with extra space after the 0

I would like to remove the extra space, how this can be done?

EDIT

I following the answer of bgoldst the extra space is gone, however now I have extra line break. I want to remove it

I found some answers for solving the extra line, however I don't want space not new line in the file

The space is introduced by the echo command because there is a space between the %NUMBER% variable and the > redirection operator. The echo command respects trailing whitespace in its command-line.

Thus, you can solve this by removing that space (and you can also remove the quotes, as well as the space between the > and the file.txt, since they are not necessary):

echo 3.3.3.%NUMBER%>file.txt

Building on the answer by bgoldst

To remove the space and the line feed:

<nul set /p=3.3.3.%NUMBER%>file.txt

See Windows batch: echo without new line for more information.
