You can find where they are in the work environment settings.

I work on AC 16 on a MacPro. When I try the File&gt;file special&gt; Merge, the merge appears to start, then fails. A similar issue comes when i try to copy/paste from one copy of AC 16 to another. I've reopened AC, and rebooted the computer. Does anyone have any idea what this could be? I recently updated to Mavericks, but I don't think it happened at the same time.</T></DIV> Tue, 16 Sep 2014 16:43:31 GMT https://community.graphisoft.com/t5/Installation-update/File-Merge-not-working/m-p/209576#M22120 Anonymous 2014-09-16T16:43:31Z https://community.graphisoft.com/t5/Installation-update/File-Merge-not-working/m-p/209577#M22121 Have you tried clearing the cache folders?
