Bulk File Replace is a free browser-based tool that lets developers and designers overwrite multiple files across a deep folder structure in seconds. The desktop app goes further with Hot Folders — automatic background importing that runs without you touching a thing.
Instead of navigating into nested project folders one by one, you drop your updated files (or a zip), pick your destination folder once, and the tool finds every matching filename automatically and overwrites them all.
Drag in individual files or a .zip. Zip contents are extracted automatically.
Select your project folder. The tool scans every subfolder for matching filenames.
Preview what will change, then copy. Backups are created automatically.
The web version runs entirely in your browser using the File System Access API. Your files are never uploaded to any server. The desktop app goes further: fully offline, no browser needed, with a native folder picker and Hot Folders that auto-imports files in the background.
The desktop app includes Hot Folders — a background automation mode that monitors any folder on your PC for new files. Drop a ZIP into your Downloads folder, walk away, and the app automatically extracts it, scans your destination for filename matches, and copies them. No clicks. No opening the app.
Hot Folders runs quietly in the system tray and sends a Windows notification summarising what was copied. You can set an unmatched folder for files with no destination match, enable a pending queue to review unmatched files manually, and configure it to delete or archive source files after processing. It restarts automatically when you reopen the app.
Point it at Downloads, a shared drive, or anywhere. ZIPs are extracted automatically. All other files scanned directly.
Runs in the system tray. Windows notification when files are copied. No window needed.
Unmatched files are held in a queue. Route them to a folder individually, in bulk, or skip them — matched files keep flowing.
Remembers your watch folder, destination, and settings. Picks up automatically when you reopen the app.
The free web version works in Chrome and Edge with no install required. It handles drag-and-drop, zip extraction, folder scanning, and timestamped backups, all from your browser.
The desktop app ($19 one-time) is a significantly more powerful tool. Unlimited files, a native Windows folder picker, full offline support, no permission prompts, no ads — and Hot Folders, which turns the whole process into a background automation that runs without you touching a thing.
