MoveFileWithProgress function

Moves a file or directory, including its children. You can provide a callback function that receives progress notifications.

To perform this operation as a transacted operation, use the MoveFileTransacted function.

Syntax


BOOL WINAPI MoveFileWithProgress(
  _In_      LPCTSTR lpExistingFileName,
  _In_opt_  LPCTSTR lpNewFileName,
  _In_opt_  LPPROGRESS_ROUTINE lpProgressRoutine,
  _In_opt_  LPVOID lpData,
  _In_      DWORD dwFlags
);

Parameters

lpExistingFileName [in]

The name of the existing file or directory on the local computer.

If dwFlags specifies MOVEFILE_DELAY_UNTIL_REBOOT, the file cannot exist on a remote share because delayed operations are performed before the network is available.

In the ANSI version of this function, the name is limited to MAX_PATH characters. To extend this limit to 32,767 wide characters, call the Unicode version of the function and prepend "\\?\" to the path. For more information, see Naming a File.

lpNewFileName [in, optional]

The new name of the file or directory on the local computer.

When moving a file, lpNewFileName can be on a different file system or volume. If lpNewFileName is on another drive, you must set the MOVEFILE_COPY_ALLOWED flag in dwFlags.

When moving a directory, lpExistingFileName and lpNewFileName must be on the same drive.

If dwFlags specifies MOVEFILE_DELAY_UNTIL_REBOOT and lpNewFileName is NULL, MoveFileWithProgress registers lpExistingFileName to be deleted when the system restarts. The function fails if it cannot access the registry to store the information about the delete operation. If lpExistingFileName refers to a directory, the system removes the directory at restart only if the directory is empty.

lpProgressRoutine [in, optional]

A pointer to a CopyProgressRoutine callback function that is called each time another portion of the file has been moved. The callback function can be useful if you provide a user interface that displays the progress of the operation. This parameter can be NULL.

lpData [in, optional]

An argument to be passed to the CopyProgressRoutine callback function. This parameter can be NULL.

dwFlags [in]

The move options. This parameter can be one or more of the following values.

ValueMeaning
MOVEFILE_COPY_ALLOWED
2 (0x2)

If the file is to be moved to a different volume, the function simulates the move by using the CopyFile and DeleteFile functions.

If the file is successfully copied to a different volume and the original file is unable to be deleted, the function succeeds leaving the source file intact.

This value cannot be used with MOVEFILE_DELAY_UNTIL_REBOOT.

MOVEFILE_CREATE_HARDLINK
16 (0x10)

Reserved for future use.

MOVEFILE_DELAY_UNTIL_REBOOT
4 (0x4)

The system does not move the file until the operating system is restarted. The system moves the file immediately after AUTOCHK is executed, but before creating any paging files. Consequently, this parameter enables the function to delete paging files from previous startups.

This value can only be used if the process is in the context of a user who belongs to the administrators group or the LocalSystem account.

This value cannot be used with MOVEFILE_COPY_ALLOWED.

MOVEFILE_FAIL_IF_NOT_TRACKABLE
32 (0x20)

The function fails if the source file is a link source, but the file cannot be tracked after the move. This situation can occur if the destination is a volume formatted with the FAT file system.

MOVEFILE_REPLACE_EXISTING
1 (0x1)

If a file named lpNewFileName exists, the function replaces its contents with the contents of the lpExistingFileName file.

This value cannot be used if lpNewFileName or lpExistingFileName names a directory.

MOVEFILE_WRITE_THROUGH
8 (0x8)

The function does not return until the file has actually been moved on the disk.

Setting this value guarantees that a move performed as a copy and delete operation is flushed to disk before the function returns. The flush occurs at the end of the copy operation.

This value has no effect if MOVEFILE_DELAY_UNTIL_REBOOT is set.

 

Return value

If the function succeeds, the return value is nonzero.

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

When moving a file across volumes, if lpProgressRoutine returns PROGRESS_CANCEL due to the user canceling the operation, MoveFileWithProgress will return zero and GetLastError will return ERROR_REQUEST_ABORTED. The existing file is left intact.

When moving a file across volumes, if lpProgressRoutine returns PROGRESS_STOP due to the user stopping the operation, MoveFileWithProgress will return zero and GetLastError will return ERROR_REQUEST_ABORTED. The existing file is left intact.

Remarks

The MoveFileWithProgress function coordinates its operation with the link tracking service, so link sources can be tracked as they are moved.

To delete or rename a file, you must have either delete permission on the file or delete child permission in the parent directory. If you set up a directory with all access except delete and delete child and the ACLs of new files are inherited, then you should be able to create a file without being able to delete it. However, you can then create a file, and you will get all the access you request on the handle returned to you at the time you create the file. If you requested delete permission at the time you created the file, you could delete or rename the file with that handle but not with any other.
