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 Windows API calls (for file-copying) preserve Alternate Data Streams (in Windows 8)? (One example would be SyncBack backup software.) I think both answers are "yes" (for NTFS volumes), 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, Thomas

Note that ReFS does *not* support ADSs.

Note > that ReFS does *not* support ADSs. And how were they in prior versions? Copying with preserving of Alternate Data Streams was supported both by Windows Explorer and Windows API calls? And there is no difference between Windows "sub-versions" (e.g. Professional, Home, etc.). I'm sorry for asking again, but would like to feel sure. Thanks, Thomas

There doesn't seem to be any changes since it was first introduced in Windows NT 3.1. http://en.wikipedia.org/wiki/Ntfs#Alternate_data_streams_.28ADS.29 > Copying with preserving of Alternate Data Streams was supported both > by Windows Explorer and Windows API calls? Depends on how the file is copied. The shell including Windows Explorer, are ADFS aware and will presere them when copying. Windows API that can copy file in a single function are mostly ADFS aware. Such as SHFileOperation, CopyFile, and CopyFileEx. Manual file copy using FileOpen, FileRead, FileWrite, etc. are not ADFS aware as they specifically chose which stream to access when opening the file. Note that in Windows, ADFS is strictly NTFS only. ADFS will not be preserved when file is being copied accross network since the system do not have control over the internal file-system of the storage on the other side of peer. There is no Windows API specifically for this and only by client- server based custom program these can be achieved. Check the MSDN library for each file function you want to use for any limitation. > And there is no difference between Windows "sub-versions" (e.g. > Professional, Home, etc.). > I'm sorry for asking again, but would like to feel sure. > Thanks, > > Thomas For ADFS, no difference.

CopyFile() and Explorer do copy ADS's.
