EDIT : How can I download a file with batch file without using any external tools?
More detailed answer of how files can be downloaded from internet in windows.
Here are two ways.The first uses bitsadmin.exe and the second hybrid jscript.net/bat (should be saved as .bat).The .net way is faster according to my tests , but creates a small .exe file that is called.And the second is a "pure" batch script.
@echo off
setlocal
call :download "http://download.teamviewer.com/download/TeamViewer_Setup_en.exe" teamv.exe
teamv.exe
exit /b %errorlevel%
:download
if "%2" equ "" (
call :help
exit /b 5
)
if "%1" equ "" (
call :help
exit /b 6
)
set url=%~1
set file=%~2
rem ----
if "%~3" NEQ "" (
set /A timeout=%~3
) else (
set timeout=5
)
bitsadmin /cancel download >nul
bitsadmin /create /download download >nul
call bitsadmin /addfile download "%url%" "%CD%\%file%" >nul
bitsadmin /resume download >nul
bitsadmin /setproxysettings download AUTODETECT >nul
set /a attempts=0
:repeat
set /a attempts +=1
if "%attempts%" EQU "10" (
echo TIMED OUT
endlocal
exit /b 1
)
bitsadmin /info download /verbose | find "STATE: ERROR" >nul 2>&1 && endlocal && bitsadmin /cancel download && echo SOME KIND OF ERROR && exit /b 2
bitsadmin /info download /verbose | find "STATE: SUSPENDED" >nul 2>&1 && endlocal && bitsadmin /cancel download &&echo FILE WAS NOT ADDED && exit /b 3
bitsadmin /info download /verbose | find "STATE: TRANSIENT_ERROR" >nul 2>&1 && endlocal && bitsadmin /cancel download &&echo TRANSIENT ERROR && exit /b 4
bitsadmin /info download /verbose | find "STATE: TRANSFERRED" >nul 2>&1 && goto :finishing
w32tm /stripchart /computer:localhost /period:1 /dataonly /samples:%timeout% >nul 2>&1
goto :repeat
:finishing
bitsadmin /complete download >nul
echo download finished
endlocal
goto :eof
:help
echo %~n0 url file [timeout]
echo.
echo url - the source for download
echo file - file name in local directory where the file will be stored
echo timeout - number in seconds between each check if download is complete (attempts are 10)
echo.
goto :eof
OR
