Hi, There is a option in Alfresco Share namely "My Files"… It says that "My Files is a unique area in Alfresco where you can create and store content, and no other Alfresco users can access it."
"My Files" is just a direct link to the logged user home folder (Repository> User Homes> username) . The Administrator user and anyone else granted at least Consumer permission will be able to view the folder in the repository and access it.
