RemarksA CopyFileManager instance can be created with or without the ability of overwriting the managed destination file. This ability is signaled be the value returned by its property CanOverwrite. When an instance is notified that a transaction is being prepared for commitment, it checks if a file having the specified path already exists. In such case, if CanOverwrite returns false, the operation cannot be executed and the transaction is forced to roll back. This also happens if the manager cannot read the content of the source file.
