I just found a lot of .txt files in my harddrive (Users/Name/AppData/Local/Oculus) from the last few days. These are 65535 KB files, and there are a few lines of normal data, but thousands of thousands of lines of these:
If you read the readme.txt "This folder contains system logs that can be packaged by the OculusLogGatherer tool and sent to Oculus Support for assistance."
And it looks like it automatically purges any older than 5 days. I don't see any harm deleting them, but I take no responsibility if you need them.
