Beyond Compare Portable Exclusive

Beyond Compare's portable version is a specialized deployment of the standard software that allows you to carry your entire comparison environment on a USB thumb drive or other removable media without modifying the host computer's registry. It offers the exact same core functionality as the installed version but is optimized for "exclusive" use cases where system modification is prohibited or multiple environments must be managed simultaneously. Key Benefits of the Portable Version

Zero System Footprint: Unlike the standard installer, the portable version does not alter the host computer's registry. It is completely self-contained, making it ideal for use on restricted work machines or public computers where you lack administrator privileges.

Unified Settings Management: All configuration files, such as BCState.xml, are stored directly in the program folder rather than in the Windows user profile. This ensures that your custom rules, syntax highlighting, and saved sessions travel with the application.

Plug-and-Play Registration: If you have a licensed copy, you can register it directly to the portable folder. For older versions like Beyond Compare 2, placing a BC2.key file in the program folder allows the software to read the license from the file rather than searching the registry.

Simplified Cleanup: Because no shared libraries are installed in system directories, you can "uninstall" the program simply by closing the application and deleting its folder.

Security & Privacy considerations

Keep all user data on portable media by default.
Encrypt stored credentials with a user-provided passphrase; do not cache plaintext secrets.
Avoid writing logs or crash dumps to host unless explicitly allowed by user.

Key behaviors

No host write policy: When enabled, the app must not create or modify files or registry keys on the host system outside the current portable drive. All configuration, logs, caches, and temporary files are stored only on the portable medium.
Auto-detect portability: Detect running from removable media and offer to enable Portable Exclusive mode with one-click; also allow manual launch option (command-line flag /portable-exclusive).
Sandboxed temp storage: Create a secure temp folder on the portable drive for all transient files (diff caches, extracted archives, thumbnails). Clean up on exit; provide configurable retention (e.g., keep last N sessions).
Profile isolation: Use a profile directory on the portable drive for all settings, rules, layout, sessions, credentials, and plugins. Allow importing/exporting profiles between portable and installed copies.
Credential handling: Optionally store credentials encrypted on the portable device (user passphrase) or use ephemeral session-only credentials that are cleared on exit. Warn users about plaintext storage if passphrase omitted.
Read-only host safe mode: If Portable Exclusive detects inability to write anywhere on the portable media (e.g., locked drive), fall back to a read-only mode that avoids any host writes and informs user of limited features (no saved sessions, no caching).
Secure cleanup: On normal exit, offer full wipe of ephemeral data (secure overwrite optional). On forced termination, provide a recovery/cleanup utility that removes leftover host-side artifacts if any were created.
Permissions & UAC: Avoid requiring elevation; when elevation is necessary for specific operations, prompt but keep core app data on portable media.
Performance: Use an index/cache on the portable drive to preserve speed; allow toggling cache size and location (if multiple removable volumes present).
Telemetry & updates: Disable automatic telemetry and background updates in Portable Exclusive; provide manual update check that can download updates to portable drive.
Enterprise controls: Provide MSI/installer flags and group-policy-compatible configuration so admins can enable or lock Portable Exclusive behavior in corporate environments.
