As Nicolas George says, "config-file" is too generic a term.
If the above is a variable assignment, then you can escape the
newlines with a backslash, like so

Do_not_write="path1/subfolder \
  path1/subfolder2 \
  ..."

Note that the backslash has to be the last character in the
line. No extra whitespace after that (this is somewhat
fragile). I prefer to put such things in here docs:

read -d '' Do_not_write <<"__END"
this
that
the other
__END

echo "Do_not_write"
=>
this
that
the other

Put attention to the quotes. In bash, type "help read" to learn
about the options (it is a builtin, it has to).

Cheers
