What It Is

Crystal Rich Ltd is a small Russian software company founded in 2007. Its website describes its mission as creating software tools that make things easier. The currently captured information shows four products: USB Safely Remove, Zentimo xStorage Manager, LockHunter, and InternetOff. Strictly speaking, it is not a typical developer platform or cloud-based development tool, but rather a collection of Windows desktop utilities.

Core Features and Ecosystem

USB Safely Remove enhances safe removal for USB and SATA devices. Zentimo xStorage Manager is described as a “Swiss army knife” for external hard drive needs. LockHunter is a Windows 32/64-bit file unlocking tool that can help when files cannot be deleted or moved because they are in use. InternetOff is used to turn off, or schedule turning off, an internet connection to reduce distractions. The captured content does not mention any API, SDK, CLI, plugin system, or third-party integrations, so its developer automation and ecosystem extensibility cannot be confirmed.

Pricing and Licensing

Pricing information is limited. LockHunter and InternetOff are clearly marked as Freeware, making them suitable for users who need free local tools. The captured text does not specify pricing, trial policies, licensing models, or payment methods for USB Safely Remove and Zentimo xStorage Manager, so the overall purchase cost cannot be assessed.

Pros and Cons

The main advantages are clear product positioning and a focus on common but well-defined pain points on Windows, including device, file, and network control scenarios. The website also provides a company address, phone number, and support email, so basic contact channels are in place. The drawbacks are that the homepage is relatively brief and does not state whether the software is open source, whether self-hosting is available, the level of documentation, release cadence, system compatibility range, or support SLA. For development teams, the lack of programmable interfaces and integration capabilities limits its value as part of a developer toolchain.

Who It’s For and Access from China

It is better suited to individual Windows users, operations staff, or developers who need to handle external storage, locked files, or temporary internet disconnection on a local machine, rather than organizations requiring team collaboration, cloud APIs, or DevOps integrations. The captured content does not provide information on access from mainland China or payment availability, so it is recommended to test network connectivity before downloading or purchasing. Alternatives include Windows’ built-in Safely Remove Hardware feature, Process Explorer, Unlocker, and USBDeview.
