Installation & setup

1. Download the portable ZIP package from the official SunlitGreen site.
2. Extract the archive directly to your USB drive or a folder on removable media.
3. Run the executable (no installer). If prompted by security settings, allow the app to run for the current user.

Recommended USB drive setup

• Use a USB 3.0 (or later) drive for faster thumbnail generation and batch operations.
• Allocate at least 8–16 GB free space if you’ll store and manage large photo sets.
• Consider organizing folders by year/event to make browsing and backups simpler.

Typical workflows

• On-the-go culling: Copy photos from a camera’s SD card to the USB drive, open them in SunlitGreen, mark favorites, delete rejects, and move selects to an “Import” folder.
• Duplicate cleanup: Run the duplicate detector on a folder or drive, review suggested matches, and remove redundant files to reclaim space.
• Metadata editing: Add or correct EXIF/IPTC info (e.g., location, keywords, photographer) before importing into a main cataloging system.
• Quick conversions: Batch-convert RAW or high-resolution images to JPEGs for emailing or uploading.

Pros and cons

• Pros: Truly portable, easy to use, low resource usage, practical duplicate finder, batch tools.
• Cons: Lacks advanced DAM features (collections, cloud sync, AI tagging), limited editing capabilities, Windows-focused.

Tips & best practices

• Always keep a backup of original photos before batch deletes or conversions.
• Run duplicate checks with conservative similarity thresholds first to avoid false positives.
• Use meaningful folder names (YYYY-MM-DD_Event) for faster scanning and manual searching.
• Pair SunlitGreen Portable with a lightweight RAW viewer if you need in-depth RAW previews.

Who it’s best for

• Travelers, field photographers, and IT-restricted users who need a portable photo utility.
• Users who want fast culling, duplicate cleanup, and simple metadata edits without installing software.

SunlitGreen Photo Manager Portable fills a niche for people who need reliable, no-friction photo management on removable media. It’s not a full digital asset manager, but as a portable utility it’s an efficient tool for organizing and cleaning up photo collections on the go.
