FAT Files That Are Opened in Exclusive Mode Can Be Moved and Deleted (326160)


The information in this article applies to:

  • Microsoft Windows CE .NET 4.0
This article was previously published under Q326160

SYMPTOMS

When a file is open on a file allocation table-based (FAT-based) medium (such as a storage card or hard disk), another process can rename, move, or delete the file. Although the file system can track open files that are renamed or moved by the file handle, some programs do not expect files to be able to be relocated while they are open.

CAUSE

The FAT file system was changed in Windows CE 3.0 hotfix 83 (in December, 2001) to permit files that are open to be moved. The change also permits files to be deleted while they are open.

RESOLUTION

This fix also contains an update to Shared Source.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.

MORE INFORMATION

The code change that is included in this update permits functions such as MoveFile and DeleteFile to operate on an open file if the file is opened with sharing permissions that permit write access (FILE_SHARE_WRITE). If FILE_SHARE_WRITE access is not granted when the file is opened, the DeleteFile and MoveFile will not work and will generate "ERROR_ACCESS_DENIED."

The Windows CE RAM file system does not permit files that are opened in exclusive write mode to be renamed or deleted.
