Depends on whose job is running in Scheduler. If the job was created using the desktop schedule browser, or by the web user interface logged in locally in the observatory (http://localhost/) then they go to the usual ACP default location for the local observatory, namely My Documents (the WINDOWS My Documents), ACP Astronomy, Images, etc. Otherwise they go to the web-visible My Documents for the web user who gave their username and password for logging in through the browser. Normally, these directories are the property of the web server and not supposed to be used locally buy the operator. Do not delete folders or any control files (.asp) that may be present in these folders or you will break the web UI. Use the My Documents section of the Web UI to do all deletions and cleanup. Anyway those folders are at Public Documents, ACP Web Data, images, web-username.
