USBFlashCopy is a small Windows utility to back up your flash drives and storage cards on the fly. It runs in the background and copies files from inserted media to a safe location on your hard drive. For experienced users USBFlashCopy can run completely invisible. No icons, no progress bars, no prompts, it just does the job. This has been added to the tools section of Research Resources Subject Tracer™ Information Blog.
