function CopyFileTo(const Source: string; const Destination: string): Boolean;
Parameters
const Source: string
Source file name.
const Destination: string
Destination file name.
Returns
Boolean - True if the file is copied, False on error.
Description
CopyFileTo is a function used to copy the file specified in Source to the file
specified in Destination.
CopyFileTo will return False if the file in Destination already exists.
CopyFileTo encapsulates the platform-specific calls needed to perform the
file copy operation. On the Windows platform, this is the Win32 API function
CopyFile. On the Linux platform, CopyFileTo uses a TFileStream instance to
create the destination file.
