Cleaning up removable drives
Removable storage devices such as USB flash drives can quickly accumulate unwanted files when you frequently move data between machines. Curb is a lightweight utility designed to remove that clutter from external media quickly and securely.
Quick rundown — what it does
Curb provides a simple drag-and-drop interface: drop your removable device onto the app and it scans and deletes unnecessary items. A small progress indicator shows the deletion status while the application runs.
Secure wipe methods available
You can choose different overwrite strategies depending on how thoroughly you want data erased:
- 35-pass overwrite (highest thoroughness)
- 7-pass overwrite
- Single-pass overwrite (usually sufficient)
- Overwrite with zeros after erasing
Generally, a single-pass wipe will remove ordinary traces of deleted files. If you need stronger protection for sensitive information, pick one of the multi-pass options.
Strengths and limitations
- Pros: Very easy to use, optimized for USB and other removable media, and includes multiple secure-deletion modes.
- Cons: Limited to external drives — it would be useful as a general-purpose file shredder for internal disks as well.
Bottom line
Curb is a straightforward, free tool for cleaning unnecessary files off USB sticks and similar devices. Its secure-removal choices make it a good pick for users who want both simplicity and configurable data wiping.
