:: To change txt file ============================
:: Because the different code, try to use type file to rebuild *.txt files.
setlocal enabledelayedexpansion
set workpath=%userprofile%\Application Data\Microsoft\Signatures
if exist %temp%\txtroot rd /s /q %temp%\txtroot
mkdir %temp%\txtroot
set txtroot=%temp%\txtroot
set txtfiles=%temp%\txtfiles.txt
if exist !txtfiles! del !txtfiles! /f /q 
dir /b "!workpath!\*.txt" >>!txtfiles!
for /f "delims=/ tokens=*" %%a in (!txtfiles!) do (
type "!workpath!\%%a">>"%temp%\txtroot\%%a"
set path="%temp%\txtroot\%%a"
for /f "delims=/ tokens=*" %%b in (%temp%\temp.txt) do echo %%b >>!path!
copy /y !path! "!workpath!\%%a">nul
)
在这里的３个文件中，对＊．rtf文件最难处理．不能直接用输出符>>进行操作：
我的处理如下：
:: To change rtf file ==============================
:: Replace the first and the second content of original *.rtf
:: By {\f0\fswiss\fcharset134 Simsun;} first line
:: By {\f1\fmodern Simsun;} second line
set rtffiles=%temp%\rtffiles.txt
if exist !rtffiles! del !rtffiles! /f /q
if exist %temp%\rtfroot rd /s /q %temp%\rtfroot
mkdir %temp%\rtfroot
set rtfroot=%temp%\rtfroot
dir /b "!workpath!\*.rtf" >>!rtffiles!
for /f "delims=~~ tokens=*" %%f in (!rtffiles!) do (
    set rtfpath="!workpath!\%%f"
    rem set rtfname=%%f
    echo Modifying !rtfpath!
    set flag=0
    for /f "tokens=* usebackq" %%g in (!rtfpath!) do (
    if !flag!==0 (echo %%g>>!rtfroot!\%%f
                  echo {\f0\fswiss\fcharset134 Simsun;}>>!rtfroot!\%%f
                  echo {\f1\fmodern Simsun;}>>!rtfroot!\%%f
                  )
    set flag=1
    )
    )
rem echo the content of original *.rtf which was begining of 3 lines but final line.
rem echo them to the folder %temp%\rtfroot
for /f "delims=~~ tokens=*" %%f in (!rtffiles!) do (
    set rtfpath="!workpath!\%%f"
    for /f "skip=3 tokens=* usebackq" %%g in (!rtfpath!) do (
    if not "%%g"=="{\*\htmltag3 \par }}" echo %%g>>!rtfroot!\%%f
    )
    for /f "delims= tokens=*" %%l in (%myfiles%\rtf.txt) do echo %%l>>!rtfroot!\%%f
    )
copy /y !rtfroot!\*.* "!workpath!\*.*">nul
