When you attempt to open a file on a Windows 2000 NTFS volume, you may receive the following error message:
If you try to copy the file, you may receive the following error message:
"The file cannot be accessed by the system"
If you right-click the file and view its properties, only the General tab may be present and other tabs (for example, the Security, Summary, Version, or Custom tabs) may be missing, depending on the file type.
Error Copying file or folder
Cannot copy filename: The file cannot be accessed by the system.
The Windows 2000 NTFS version 5.0 file system supports reparse points that can be used to extend the capabilities of the file systems. When a reparse point is added to a file or folder, an NTFS $Symbolic_Link attribute contains a unique TAG value. This unique TAG value is associated with an application or filter driver. When an application requests that a file be opened, NTFS passes the I/O request to the correct filter driver responsible for that specific TAG. If the filter driver that is responsible for opening the file is not installed or running, the error message is displayed.
Restoring a full backup of a remote storage managed volume to an unmanaged system restores reparse points.
Before you can determine which filter driver or application is associated with the file, you need to know what the TAG value is. No tool currently does this, but the following two native Windows 2000 services use reparse points: Remote Storage and Remote Installation Service (RIS). If you installed either of these services and then later removed them, or if either of the services is currently stopped, you need to reinstall or restart the service before you can gain access to the affected files.
