Opera Cache

Not sure if this has been covered elsewhere, I couldn't find anything, but I am wondering if there is anyway to have the Opera cache folders trimmed down at regular intervals. I have noticed that after using it for a few days that the folder can grow to over 1 GB. I am in no way very technical about the running of the portable apps, but wondering if I use the "AdditionalParameters=--disk-cache-size=" setting it might help.

I regularly go in and delete the thousands of cache files that build up, but thought there might be an easier way.

Thanks for your time, and keep up the great work.
