  • To clarify, the HRU files are used as part of the Hyper-V Replication function. They are copies of everything written to the VHD/VHDX virtual disks and are synced to the replication server. Manually deleting them is not a good idea.

    Occasionally they can be left behind if Replication is not disabled cleanly. So, if you have disabled or are not currently using Hyper-V Replication and see HRU files with older dates, they can likely be deleted.
