加密windows系統的文件夾內容，加密後的文件夾內容只有輸入密碼後，才能看到。先上代碼：
cls
@ECHO OFF
title Folder Private
if EXIST "Locker" goto UNLOCK
if NOT EXIST Private goto MDLOCKER
:CONFIRM
echo Are you sure you want to lock the folder(Y/N)
set/p "cho=>"
if %cho%==Y goto LOCK
if %cho%==y goto LOCK
if %cho%==n goto END
if %cho%==N goto END
echo Invalid choice.
goto CONFIRM
:LOCK
ren Private "Locker"
attrib +h +s "Locker"
echo Folder locked
goto End
:UNLOCK
echo Enter password to unlock folder
set/p "pass=>"
if NOT %pass%== 你的密碼 goto FAIL
attrib -h -s "Locker"
ren "Locker" Private
echo Folder Unlocked successfully
goto End
:FAIL
echo Invalid password
goto end
:MDLOCKER
md Private
echo Private created successfully
goto End
:End
將這段代碼複製到文本編輯器，記事本或者Editplus文本編輯器，設置密碼，然後保存後綴爲.bat即可。
文件夾的加鎖和解鎖，重複上面的步驟即可。
