Yes, and the answer was a week ago: just put "r" before  the string.
r"C:\programs\util"

And it worked till now. So why should I replace backslashes with
forward slashes?
There is one issue that I can't write \ on the end:
r"C:\programs\util\"

But since I know it's a path and not a file, I just write without trailing \.
