Let’s explore how it works and how businesses are using it to save time.

What is Rofiles?
Rofiles is the robot for your files, a lightweight yet powerful file automation tool developed by Namtuk, designed to monitor
folders in real-time and automatically apply predefined actions, like adding stamps/watermarks to PDF files.
The best part? It requires no user interaction once configured. Drop a file into a hot folder, and Rofiles does the rest.
Add Watermark on mass PDF files, simply
With Rofiles, watermarking becomes a background operation. Here's how the process works:
1. Define a Hot Folder Select a folder on your system or network that Rofiles will monitor continuously.
2. Add the action 'Stamps/Watermark', in the folder's scenario:
Customize watermark text (like "CONFIDENTIAL", "DRAFT", "Received on Saturday, August 30, 2025", position, opacity, font, and more.
3. Get Watermarked Output
Choose the action(s) for output, it can be a local or network folder, an email, or upload to your FTP, send it to Slack or Telegram, or simply print it.
4. Drop Your PDFs
As soon as a PDF lands in the hot folder, from a user, scanner, or any software, Rofiles adds the watermark automatically.
No scripting. No pop-ups. No time lost.
