Important: Beware of applications like "Clean My Mac" or "CCleaner"
We recommend VTPro users not to use applications such as "Clean My Mac", "CCleaner" or the like. Since these applications could delete the folders and files of the Projects of your virtual tours. If this happens, unless you have a copy or "Project backups with media", you could lose those tours and not recover them.
