CMPFileManager deals with all file operations, such as copying the file from source to sink, during copy user can always cancel copy, allowing to move a file instead of copy if needed, etc.

Below is the example code which demostrate CMPFileManager usuage.

_LIT(oldFile,"Old File Name");
_LIT(newFile,"New File Name");
 
void CTestMPFileManagerAppUi::ContructL()
{
...
 CMPFileManager * iFileMgr = CMPFileManager::NewL();
...
}
 
void CTestMPFileManagerAppUi::StartCopyOperationL()
{
    //Starts asynchronous copy operation
    iFileMgr->StartCopyOperationL(this,oldFile,newFile);
}
void CTestMPFileManagerAppUi::CancelCopy()
{
    //Cancels asynchronous copy operation
    iFileMgr->CancelCopy();
}
