Question

I’m using CopyFileEx to copy files with that ability. Is there anything like it for moving files? Remember that not every move is fast – moving to a different drive is actually a copy.

The solution I have now is to copy-and-delete-the-original if the move is to a different root directory, and to simply move (and hope it’s really just a change in the pointer to the file) if it’s to the same root directory.

Is there a straightforward solution (like CopyFileEx)?

Answer 1

MoveFileTransacted or MoveFileWithProgress might be more suitable? I believe that can be cancelled.

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

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.
