QFile Copy Video File problem

[digimonkey]

Hi,
I'm trying to use QFile::copy to copy a video file to another folder (*.mp4 video). It copies but the file seems corrupted, it wont open.
I'm using

QFile::copy(videoPath,copyPath);

QFile::copy(videoPath,copyPath);

To copy to clipboard, switch view to plain text mode 

where the videoPath is the original video path (C:/rec/untitled 01.mp4) and the copyPath is the new folder that already exists (C:/rec/copy/newname.mp4)

Is there anything I should knew about copying Video Files with QFile?

Thank you in advance.

QFile::copy() doesn't care what type of file it is. What is the return code from QFile::copy()?
