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

ID: Q117160

The information in this article applies to:

Microsoft Windows NT operating system 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.
