The product unique features are:


At the same time, it is important to note that HHD Software DupeCare is NOT:

  • A backup software. Deduplicated data is stored on the same volume and cannot be considered a safe backup. Always use backup for sensitive data. Backup may be effectively configured for deduplicated folders using OS features or third-party backup software products.
  • Data compression software. Depending on the nature of stored data, the effective compression ratio may not be as good as offered by the best compression utilities. Nevertheless, when files with a large number of duplicated content are stored, HHD Software DupeCare may show orders of magnitude better compression ratio while working much faster than compression software.

HHD Software DupeCare requires 64-bit Windows 10 (version 1809 or later) or Windows 11. x86-64 and ARM64 CPUs are supported.

Deduplicated folder must reside on NTFS or ReFS formatted volume.
