    • Remember to also update the cleanup agents which look to delete old file based media entries. These are referenced in the CleanupAgent.
  • Move the temp folder

For this reason /temp needs to live as /temp under the site root. With some help from support they concluded that rather than a virtual directory, a symlink was the best approach. For details on setting one up via powershell, seeĀ As part of our startup scripts we included calling the script to shift things around.
    • The clue a folder is a symlink is the icon will change ala:
