Scan folders recursively, verify duplicates by name or SHA-256 content, keep the newest or oldest copy, and move selected files safely to Trash. Duplicate File Checker is a private, on-device utility for finding redundant files. Choose a folder and the app recursively scans every regular file in its subfolders, revealing matching names and byte-for-byte duplicate content. Accurate duplicate detection • Identical Content filters by file size first, then verifies complete files with SHA-256 • Same Name gathers matching filenames so you can compare location, size, and modification date before removing anything Flexible keep rules • Keep the newest file or keep the oldest file • Selections update automatically when you switch comparison modes • Review and change any selection before cleanup Protect intentional copies • Limit content matching to files in the same folder • Files are grouped only when their complete parent-folder paths match • Keep valid copies that belong in separate projects or directories Safer cleanup • Selected files are moved to the system Trash, never permanently erased by the app • See the number of selected files and estimated recoverable space before acting • Expand or collapse every result group with one click Fast and private • Scanning and verification happen entirely on your device • No uploads and no account required • Large files are read in chunks to reduce unnecessary memory use Use Duplicate File Checker with documents, photos, videos, archives, and other regular files whenever you need a careful storage cleanup.
