Copying of Alternate Data Streams RRS feed

  • Question

  • Hello,

    I read that ADS (Alternate Data Streams) are still supported in Windows 8.

    Will copying files with Windows Explorer preserve Alternate Data Streams (in Windows 8)?
    Will copying files with applications which do file-copy Windows API calls preserve Alternate Data Streams (in Windows 8)? (One example would be SyncBack backup software.)

    I think both answers are "yes", but would like to ask to be sure.
    I'm using Windows 8 Pro 64bit (but there should be no difference between different Windows 8 versions, right?)

    Thanks.

    The answer is "it depends". So if you copy NTFS -> NTFS it should work. If you'll do NTFS -> ReFS or FAT copy you'll copy main stream only.

  • Thanks for your answer.

    Do you mean both Windows Explorer copying, and Windows API calls copying? On all Windows 8 versions (Pro or other, 32bit or 64bit)?
