## AI overview

A ReactOS GSoC progress report explains that Windows did not initially recognize newly written file data because the implementation updated the NTFS $DATA attribute without updating the associated $FILE_NAME directory index entry.

## Source excerpt

Mid-term evaluations opened up yesterday, and naturally I've been super-busy this week, making sure I've earned my keep! ;) Getting the New Size Recognized in Windows Recall that I ended last week being able to extend a file's size in ReactOS, but Windows wasn't showing the newly written data when opening the file in notepad. My mentor Pierre and forum member Pathoswithin both suggested, independently, that my problems with extending a file might be caused by only increasing the size of the $DATA attribute and not also modifying the appropriate $FILE_NAME attribute associated with the file.
