Text files that are so big

Hi everyone. Can anyone explain to me what are these text files being generated for? They are so big and cannot even open by any word editor programs. They are generated within the folders where I am saving my d5 projects. Just wondering if they are important to keep?

Hi there, the text files can be temporary files that D5 Render will delete after project files are saved. I am not sure why those files were not deleted on your device, are you using a network drive that has something like backup feature?
Also, please send a log file to me for analysis, we can narrow down the issue cause of this problem.
