How to log file copying process in Inno Setup

Question

During the installation, I need to copy some files from folder to another, how can I be sure, that this copying process was successful?

FileCopy(ExpandConstant('{src}\copy.txt'), ExpandConstant('{app}\test_success.txt'), false);

Is there any possibility to log copying process during installation.

SetupLogging does not provide any information about copying process during the installation

Thank You in advance
