DuoBolt is a high-performance desktop application for identifying and removing duplicate files with absolute precision and consistency. The analysis engine uses multi-threaded BLAKE3 to process folders, code bases, design files, external drives, and NAS volumes with uniform accuracy across all data sizes. The workflow follows a straightforward sequence: select locations to analyze, review duplicates with clear contextual grouping, safely delete selected files. All deletions are sent to the system Recycle Bin/Trash and can be undone. DuoBolt performs byte-by-byte comparisons without relying on file names, metadata, or heuristics. The results maintain predictability, verifiability, and suitability for professional environments where correctness is essential. The application includes a 7-day fully functional trial period.
