The files are created on a host machine, I have the log files on the master, several tests projects are run on the host machine and every time it's wiped clean, I have potentially 100's of files to change and doing a procedure that updates all the files is way more effective
Then, alternatively, rather than extracting them from the log, in your script code, save the file to a centralized location.
I'm not saying it's not possible to extract the files from the log (I've not had need to) but the code for doing so is probably going to be a bit complex to be able to read the native log format, find the reference to the file, extract and decode the bit-stream, etc. So, rather than overcomplicating things, pick a shared directory location on some centralized file server, write the files to that, and then use that location as your source for processing and updating the files.
