To fully specify the default data stream, use " filename::$DATA", where $DATA is the stream type. See below for a list of stream types.īy default, the default data stream is unnamed. Stream type specifier values always start with the dollar sign ($) symbol. Users therefore can't create new stream types, but they can open existing NTFS file system types. The stream type (also called an attribute type code) is internal to the NTFS file system. When specified from the Windows shell command line, the full name of a stream is " filename: stream name: stream type", as in the following example: "myfile.dat:stream1:$DATA".Īny characters that are legal for a file name are also legal for the stream name, including spaces. If a file being copied has a data stream and the network redirector is used, the file can only be copied if the client has both the read permission and the read attributes permission. If another process has opened a stream without the FILE_SHARE_DELETE permission, you cannot open the file for delete access. When delete access is requested on a file, the operating system checks for delete access on all open streams in a file. Sharing modes are also maintained per stream. Opportunistic locks are maintained per stream. The file times for a file are updated when any stream in a file is updated. There are no file times associated with a stream. GetFileAttributes, GetFileAttributesEx, GetFileAttributesTransacted, GetFileInformationByHandle, and GetFileInformationByHandleEx return the sparse state of the default data stream if no stream is specified. The FILE_ATTRIBUTE_SPARSE_FILE attribute on the file is set in the dwFileAttributes member of the WIN32_FIND_DATA structure returned from the FindFirstFile, FindFirstFileEx, and FindNextFile functions if any of the streams have ever been sparse. The valid data length (VDL) is the number of bytes that are initialized from the allocation size for the stream.Įach stream also maintains its own state for compression, encryption, and sparseness.The actual size is the number of bytes that are being used by a caller.The allocation size is the amount of disk space that is reserved for a stream.For example, you can create a stream that contains search keywords, or the identity of the user account that creates a file.Įach stream that is associated with a file has its own allocation size, actual size, and valid data length: In the NTFS file system, streams contain the data that is written to a file, and that gives more information about a file than attributes and properties. Which shortcuts you’ll want depends on what media center program you tend to use on your computer, because they often use different keyboard shortcuts.A stream is a sequence of bytes. This is just a start, of course: you can assign all sorts of specific things. The “Back” button on the remote to the “Backspace” key, so you can go back a page in web browsers or up a level in media center applications like Kodi or Plex.The “Play” button to the spacebar, so you can pause or play media in basically any program ever.The “OK” button on the remote to the “Enter” key, so you can open things in the start menu or your media center application of choice.Direction buttons on the to the arrow keys, so you can explore the start menu, as well as media in your media center application of choice.Note that simply checking the Windows key won’t work. With this you launch the start menu from your couch. The “Windows” button on the remote to the “Control” and “Esc” keys, which is an alternative shortcut for the “Windows key” on the keyboard.There’s a chance you know exactly which keyboard shortcuts you want to map to which buttons, but if not, here are a few we think everyone will find useful. Advanced MCE Remote Mapper Tool gives you a lot of freedom, which can be overwhelming.
