File I/O Functions Misbehave After NTFS Path Element Renamed |
Q268897
The information in this article applies to:
- Microsoft Win32 Application Programming Interface (API), used with:
- the operating system: Microsoft Windows 2000
SYMPTOMS
On a Windows 2000 NTFS volume, if a folder within a file path is renamed to a truncated version of the original folder name, some file I/O operations may continue to behave as if the old path is still valid.
For example, consider the following file path:
C:\Development\Bin\App.exe
If the folder "development" is renamed as "dev", some functions may still be able to access the file using the full original path name. That path should now be invalid, but it continues to work until the computer is restarted.
The nature of the unexpected behavior depends on the API being used. For example, GetFileAttributes() will continue to return attributes for the file based on the old name. In this case, the API continues to succeed when it should fail.
On the other hand, an attempt to create a new C:\Development\Bin folder through the use of CreateDirectory() will fail with "ERROR_ALREADY_EXISTS". In this case, the API fails when it should succeed.
CAUSE
When a folder name is truncated, its corresponding hash value is not being properly removed from the NTFS hash table on Windows 2000.
RESOLUTION
To resolve this problem, obtain the latest service pack for Windows 2000. For additional information, please see the following article in the Microsoft Knowledge Base:
