File Size and Date Reported Incorrectly On NTFS Drive (125385)
The information in this article applies to:
- Microsoft Windows NT Workstation 3.5
- Microsoft Windows NT Server 3.5
This article was previously published under Q125385 SYMPTOMS
File Manager and the Windows NT Command Prompt DIR command incorrectly
report file date, time, and size information.
CAUSE
This problems occurs when the file date, time, and size information stored
in the directory entry for a file is not updated from the file date, time,
and size information stored in the file record. As a result, file date,
time, and size data are not displayed correctly when a non-specific or
wildcard DIR command (one that does not explicitly specify a single file
name) is issued.
This problem only affects files on Windows NT machines which have been
modified by non-Windows NT client workstations.
WORKAROUND
To work around this problem, explicitly specify the file name in a DIR
command, or open and close the file exhibiting the problem with an
application.
MORE INFORMATION
The NTFS file system maintains the current date, time, and size in the file
record. It also contains duplicate information in the directory entry for
quick reference by applications that do not need to access the actual file
data (such as the DIR command). This results in a substantial performance
improvement when only the file date, time, or size is being requested.
For performance reasons, when an application has a file open NTFS ignores
the directory copy of file date, time, and size information. When the file
is closed, or when an application makes an explicit request to update the
information, the directory copy of the information is updated.
STATUS
Microsoft has confirmed this to be a problem in Windows NT version 3.5.
This problem has been corrected in the latest U.S. Service Pack for Windows
NT version 3.5. For information on obtaining the Service Pack, query on the
