It's a minor thing, but there are items like FormData, where the File object has more semantics than Blob: "If you specify a Blob as the data to append to the FormData object, the filename that will be reported to the server in the 'Content-Disposition' header will vary from browser to browser" FileEntry.file( callback ) will return a new file object, but is quite a bit of extra work. >>> Please review the editor's draft at: >>> http://dev.w3.org/2006/webapi/FileAPI/ > >> I want to see the FileSaver (and a new, FileSaverStream) interface >> moved >> into the File API. > > You mean, you find difficulty in the way they're set up now? By "moved" you mean you want them part of the same specification? Why? The File API Blob constructor obsoletes File Writer BlobBuilder. The FileWriter and FileWriterSync methods are noted in the File Writer API as something that ought to be moved to the File System API. That only leaves one method, FileSaver. FileSaver only requires the File API. Yes, I'm suggesting that FileSaver should be part of the File API specification, and FileWriter should be part of the FileSystem specification, then the File Writer API document can be retired. Microsoft has experimented with window.navigator.msSaveBlob and msSaveOrOpenBlob in IE10, as mentioned here: http://msdn.microsoft.com/en-us/library/ie/hh673542(v=vs.85).aspx Note that they've included it in the File API section examples. Google hasn't implemented FileSaver yet, they seem to be waiting for consensus: http://code.google.com/p/chromium/issues/detail?id=65615 With FileSaver and FileSaverStream in the main File API document, I'd imagine we could develop quicker and cleaner consensus, and it will be easier for developers to understand its use and availability.
