DeleteFileTransactedA function (winbase.h)

[Microsoft strongly recommends developers utilize alternative means to achieve your application’s needs. Many scenarios that TxF was developed for can be achieved through simpler and more readily available techniques. Furthermore, TxF may not be available in future versions of Microsoft Windows. For more information, and alternatives to TxF, please see Alternatives to using Transactional NTFS.]

Deletes an existing file as a transacted operation.


BOOL DeleteFileTransactedA(
  [in] LPCSTR lpFileName,
  [in] HANDLE hTransaction


[in] lpFileName

The name of the file to be deleted.

By default, the name is limited to MAX_PATH characters. To extend this limit to 32,767 wide characters, prepend "\\?\" to the path. For more information, see Naming Files, Paths, and Namespaces.


Starting with Windows 10, Version 1607, you can opt-in to remove the MAX_PATH limitation without prepending "\\?\". See the "Maximum Path Length Limitation" section of Naming Files, Paths, and Namespaces for details.

The file must reside on the local computer; otherwise, the function fails and the last error code is set to ERROR_TRANSACTIONS_UNSUPPORTED_REMOTE.

[in] hTransaction

A handle to the transaction. This handle is returned by the CreateTransaction function.

Return value

If the function succeeds, the return value is nonzero.

If the function fails, the return value is 0 (zero). To get extended error information, call GetLastError.


If an application attempts to delete a file that does not exist, the DeleteFileTransacted function fails with ERROR_FILE_NOT_FOUND. If the file is a read-only file, the function fails with ERROR_ACCESS_DENIED.

The following list identifies some tips for deleting, removing, or closing files:

  • To delete a read-only file, first you must remove the read-only attribute.
  • To delete or rename a file, you must have either delete permission on the file, or delete child permission in the parent directory.
  • To recursively delete the files in a directory, use the SHFileOperation function.
  • To remove an empty directory, use the RemoveDirectoryTransacted function.
  • To close an open file, use the CloseHandle function.
If you set up a directory with all access except delete and delete child, and the access control lists (ACL) of new files are inherited, then you can create a file without being able to delete it. However, then you can create a file, and then get all the access you request on the handle that is returned to you at the time you create the file.

If you request delete permission at the time you create a file, you can delete or rename the file with that handle, but not with any other handle. For more information, see File Security and Access Rights.

The DeleteFileTransacted function fails if an application attempts to delete a file that has other handles open for normal I/O or as a memory-mapped file (FILE_SHARE_DELETE must have been specified when other handles were opened).

The DeleteFileTransacted function marks a file for deletion on close. The file is deleted after the last transacted writer handle to the file is closed, provided that the transaction is still active. If a file has been marked for deletion and a transacted writer handle is still open after the transaction completes, the file will not be deleted.

Symbolic links:  If the path points to a symbolic link, the symbolic link is deleted, not the target. To delete a target, you must call CreateFile and specify FILE_FLAG_DELETE_ON_CLOSE.

In Windows 8 and Windows Server 2012, this function is supported by the following technologies.

Technology Supported
Server Message Block (SMB) 3.0 protocol No
SMB 3.0 Transparent Failover (TFO) No
SMB 3.0 with Scale-out File Shares (SO) No
Cluster Shared Volume File System (CsvFS) No
Resilient File System (ReFS) No

SMB 3.0 does not support TxF.


The winbase.h header defines DeleteFileTransacted as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.


Requirement Value
Minimum supported client Windows Vista [desktop apps only]
Minimum supported server Windows Server 2008 [desktop apps only]
Target Platform Windows
Header winbase.h (include Windows.h)
Library Kernel32.lib
DLL Kernel32.dll
