Q117160: File Manager Shows Wrong File Size for Files Larger than 4G

Article: Q117160
Product(s): Microsoft Windows NT
Version(s): 3.1
Operating System(s): 
Keyword(s): kbtool
Last Modified: 08-AUG-2001

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Windows NT Server version 3.1 
- Microsoft Windows NT Workstation version 3.1 
- Microsoft Windows NT Advanced Server, version 3.1 
-------------------------------------------------------------------------------

SYMPTOMS
========

File Manager shows the wrong file size for files that are greater than 4 GB in
size. The file size shown is the difference between the file's actual size and 4
GB. For example, if the actual file size is 4,819,255,296 bytes, File Manager
shows the size as 524,288,000:

    4,819,255,296 (file size)
  - 4,294,967,296 (4 GB)
  ---------------------------
      524,288,000

The DIR command displays file sizes correctly.


CAUSE
=====

File Manager ignores the high DWORD for computing the file size.


STATUS
======

Microsoft has confirmed this to be a problem in Windows NT version 3.1. We are
researching this problem and will post new information here as it becomes
available.
