Encounter logging is a staple of endgame PvE progression in MMORPGs (1, 2, 3). With the introduction of addons, console players gained the ability to generate logs via the /encounterlog command. However, the security model of these platforms prevents consumers from accessing or exporting game save and log files. It seems that there is no way to access the logs directory, even through the addon API. This also means that once a log file has been generated on a console, it cannot be selectively deleted. Would it be possible for a dev to look into this?

If addons were granted read access to compressed representations of these files, then perhaps the data could be exfiltrated less directly using screen capture. Eg; by encoding the log lines as a slide show of QR codes that the player screen captures, then decodes back to csv on their PC.
Example: A more elegant solution would be for ZOS to serve these files directly; uploading the log to an FTP server upon completion of logging and then generating a temporary URL that the player enter into their browser to initiate a download.

Another solution could be to license the esologs' uploader tool and package it into the game client itself.
