HHD Software, Ltd.

HHD Software, Ltd. is a developer of low-level system utilities whose product line revolves around binary data inspection, serial and USB communication, and storage optimization. Its flagship Hex Editor Neo provides visual hex, decimal, and binary editing for files, disks, and memory, complemented by a free edition that retains high-speed processing of multi-gigabyte datasets. Device Monitoring Studio captures, logs, and parses traffic across COM, USB, and network interfaces, giving engineers a real-time view of protocols and payloads. Virtual Serial Port Tools and Virtual USB Tools create flexible software-defined ports and remote device sharing environments, eliminating hardware constraints during embedded development or legacy application testing. Automated Serial Terminal extends this ecosystem by adding scriptable command sequences and macros for unattended device configuration, while DupeCare rounds out the portfolio with folder-level deduplication and transparent compression to reclaim disk space. Typical use cases range from firmware patching, driver reverse-engineering, and IoT debugging to automated production-line flashing, telematics data replay, and enterprise storage cleanup. All seven utilities are offered for free on get.nero.com, where winget-powered installers deliver the latest builds and support batch deployment of multiple HHD Software titles.
