Making apps or games portable is always a fun job... I figured out a easy way to fake an app being installed while trying to make minecraft fully portable, instead of copying to %AppData% Code: ::::::::::::::::::::::::::::::::::::::::: :: Automatically check & get admin rights ::::::::::::::::::::::::::::::::::::::::: @echo off CLS ECHO. ECHO ============================= ECHO Running Admin shell ECHO ============================= :checkPrivileges NET FILE 1>NUL 2>NUL if '%errorlevel%' == '0' ( goto gotPrivileges ) else ( goto getPrivileges ) :getPrivileges if '%1'=='ELEV' (shift & goto gotPrivileges) ECHO. ECHO ************************************** ECHO Invoking UAC for Privilege Escalation ECHO ************************************** setlocal DisableDelayedExpansion set "batchPath=%~0" setlocal EnableDelayedExpansion ECHO Set UAC = CreateObject^("Shell.Application"^) > "%temp%\OEgetPrivileges.vbs" ECHO UAC.ShellExecute "!batchPath!", "ELEV", "", "runas", 1 >> "%temp%\OEgetPrivileges.vbs" "%temp%\OEgetPrivileges.vbs" exit /B :gotPrivileges :::::::::::::::::::::::::::: ::START :::::::::::::::::::::::::::: setlocal & pushd . REM put here code as you like ren %AppData%\.minecraft minecraftbackup >nul mklink /D "%AppData%\.minecraft" "%~dp0.minecraft" reg add "HKCU\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers" /v "%AppData%\.minecraft\minecraft launcher\Minecraft Launcher.exe" /t REG_SZ /d "~ PERPROCESSSYSTEMDPIFORCEOFF HIGHDPIAWARE" /f start "" "%AppData%\.minecraft\minecraft launcher\Minecraft Launcher.exe" rd /q %AppData%\.minecraft ren %AppData%\minecraftbackup .minecraft>nul The code is below the "REM put here code as you like" line, but you need to remember to set the .cmd to be ran as admin, you could in theory use a SFX to do the same job, but I really wanted to just post how using mklink can link to a physical folder on another drive and any reads or writes to that folder will be to the folder/drive your on, in my case D:\ppGames\Minecraft, but as minecraft forced users to install to "%AppData%\.MineCraft" I just wanted to save the copy from happening and in turn, figured it would work for any app that uses the %AppData% etc, just try to use deeper sub folders as using %AppData%\Adobe would make other Adobe apps access the portable app, instead try to keep them deeper in the folders... As you can see it will clean itself up once you quit the app, but if you run them both at the same time, you could end up with excess files and other apps complaining about missing files. Oh and the reg link is just in there to disable DPI, as minecraft seamed to be bigger than the screen as I use 125% DPI. this fixes that too.
