I'm successfully splitting %PATH% into multiple lines like this

set t=%PATH:;=^&echo.%

then this displays each path in new line nicely, just as I want:

echo %t%

However when I want to write variable into a file

echo %t% >paths.txt

only last line is written to the file.

What am I doing wrong?

Update

Turns out the set t=%PATH:;=^&echo.% command does not replace ; characters with line breaks (as I was told) but instead replaces it with the &echo.‌​ command, which is later executed.

You need to surround the last echo with ( and )

(echo %t%) > paths.txt

Corrected batch file (test.cmd):

@echo off

setlocal

set t=%PATH:;=^&echo.%

echo %t%

(echo %t%) > paths.txt

:endendlocal

Example usage:

A simpler solution

This solution does not require any brackets in the path to be escaped.

test.cmd:

@echo off

setlocal

for %%i in ("%path:;=";"%") do (

  echo %%~i >> paths.txt

)

:endendlocal

And from the command line:

for %i in ("%path:;=";"%") do echo %~i >> paths.txt

Yours t should not store special control characters as a part of path like ", &, |, % and so on.
If so, then you can just replace the ending ) character having interference with the parser:
