The portable ZIP contains only the files needed to run codex-barbar.exe:
codex-barbar.exe
LICENSE
UPSTREAMS.md
README.md
README.zh-CN.md
PORTABLE.md
No installer or registry change is made. The executable is the same Windows x64 desktop binary that the NSIS installer deploys.
The portable build writes all accounts, cache, logs, and settings to
%LOCALAPPDATA%\codex-barbar, exactly like the installed build. It never
writes data beside the executable. To remove the app's data, close
codex-barbar and delete %LOCALAPPDATA%\codex-barbar.
Unblock the downloaded ZIP before extraction (right-click the ZIP, then Properties, and check Unblock). Windows SmartScreen may warn because the unsigned portable binary is downloaded from the internet.
The portable build does not update itself. Replace the extracted files with the new release and keep the data directory untouched.
