Ratool (Removable Access Tool) is a free and lightweight utility designed to give you complete control over USB storage devices on your Windows PC. Unlike stricter tools that simply block all drives, Ratool lets you choose between blocking, enabling, or setting USB drives to read-only mode. This makes it one of the most flexible freeware solutions for protecting your computer against data theft and malware spread via removable media.

Why Would a Beginner Use Ratool?
USB flash drives are one of the easiest ways to transfer files—but also one of the most common ways for malware to spread or for sensitive data to be stolen. Beginners may not want a complicated antivirus suite or a background service running all the time. Ratool offers a clean interface where you can simply select how USB drives should behave: blocked, enabled, or read-only. It’s portable, easy to use, and requires no installation, which makes it perfect for both home and small office users.
Main Features of Ratool
- Block all USB drives – Prevents any USB storage device from being recognized by your PC.
- Read-only mode – Allows files to be read from USB devices but prevents new files from being written, reducing malware risks.
- Enable USB drives – Switch back to normal access whenever you need to copy or transfer files.
- Password protection – Lock Ratool’s settings so only authorized users can change access modes.
- Selective blocking – Block all USB drives by default while allowing access only to trusted or whitelisted devices.
- Portable software – No installation required; you can run it directly from a folder or even a USB drive.
How to Use Ratool
Step 1. Download Ratool from the official Sordum website or a trusted freeware source.
Step 2. Extract the downloaded ZIP file and run the Ratool executable (no installation is required).
Step 3. Choose your preferred USB access mode:
- Block USB Storage Devices – Completely blocks USB storage.
- Allow Read Only – Files can be read but not copied to or from the USB drive.
- Allow Read & Write – Restores normal access to removable drives.
Step 4. Apply password protection if you don’t want others to change the settings.
Step 5. Click Apply Changes and close the tool—it will enforce your chosen policy even after you restart your PC.
Safe Use Tips for Beginners
While Ratool is powerful, you should still practice basic USB safety. Never connect unknown flash drives, always keep your Windows security patches updated, and scan your system regularly with a free malware scanner. Ratool is most effective when combined with safe computing habits.
