The main difference between the free and paid versions of the SysInfo VHD Recovery Tool is the ability to save recovered data. The free demo version lets users access the software's recovery features, scan corrupted VHD/VHDX files, and preview the recoverable files and folders, but it does not allow the recovered data to be saved locally. The full paid version unlocks the complete recovery functionality, allowing users to save recovered files and repaired VHD disk images to a desired location. Both versions support features such as fixed and dynamic VHD recovery, Standard and Advanced scanning modes, MBR and GPT partitions, multiple recovery modes, and various file systems. Therefore, the free version is useful for checking whether the tool can detect your data, while the paid version is required when you want to save and restore the recovered data.
