SYMPTOMS

The wrong file size will be displayed when you view a Macintosh System executable or font file on a Services For Macintosh (SFM) volume on a Windows NT Server computer.

This problem will occur in all versions of Windows NT when you use DIR from the command prompt or in File Manager. This will also occur when viewing a Macintosh executable file with Windows NT 4.0 Explorer. A Macintosh client shows the correct file size.

CAUSE

Macintosh files have both a Data Fork and a Resource Fork. Windows NT gets the file size info from the Data Fork. If no information is available in the Data Fork, the file size displayed is zero. Both Macintosh executable files and font files have 0 bytes listed in the Data Fork, so their size is displayed as 0 bytes.

STATUS

Microsoft has confirmed this to be a problem in Windows NT Server versions 3.1, 3.5, 3.51 and 4.0. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
