  • Stream and Advanced Attributes Comparison

    Does Beyond Compare detect differences in:
    1. streams other than the primary data stream?
    2. advanced filesystem attributes like Encryption, Deduplication, etc.?

    BC3 does not currently support comparing alternate data streams. We do support copying the NTFS security descriptors as a Session Setting, Handling option.

    We do not have a deduplication scan; BC3's Folder Compare loads two directories side by side and compare the contents between these locations.

    Our trial is fully featured and available for testing here:

    We have a summary tutorial video here:

    Please let us know if you have any questions.

      to clarify, a file may be marked for NTFS you detect if that flag is changed?

      similar question for NTFS deduplication in Windows 2012.

      Thanks for sharing your insights!

        Neither of these attributes are compared. You can find the list of standard attributes in our Session Settings, Comparison tab: Read Only, System, Hidden, Archive.

        Windows 2012 deduplication can sometimes results in files handled as symbolic links instead of files by the OS. If this is occurring, you will need to enable the Handling tab's "Follow Symbolic links" to treat them as their target instead of the link.
