Well, I know my files came from the new client. I deleted them all before running the new one and watched the files get generated as I loaded / closed worlds and then closed the client. Then I deleted them again and went through the process again, experiencing the same file generation.

So I am going to say it's still an issue with the new client. However, it's still unfinished so maybe it is something they will get fixed.

I am still experiencing it. Granted I just tried out the new client just this moment so I could respond to your question with feedback so I don't know how bad it will be with prolonged use.

In the new client (13w17a) It will generate a new output-server.log file every time I open and close a world. However, unlike the previous client, it does delete 1 or 2 of the files when the game is closed but not all of them.

After loading and quitting my survival world a few times and then closing the game, I am left with the following files:

output-client.log
output-server.log
output-server.log.1
output-server.log.1.lck
output-server.log.2
output-server.log.lck

I am assuming all of those files were to be disposed of once the game was closed, correct?

So I would imagine that if I played like I normally do for hours at a time switching between test worlds that the folder would fill up pretty fast.

Had this happen to me earlier today but I assumed it was because I exited my world but left Minecraft running minimized all night. However, I often leave Minecraft running for days without problems so I'll comment.
