In the preferences "Folders" the directories that can be accessed by #Gazer can be defined. The "+" button can be used to add more directories that #Gazer can access without asking again.
You can also revoke this access by selecting the corresponding directory in the list and removing it by clicking on the "-" button.
The option "Always ask for directory access" makes sure that if #Gazer has not been granted permission to access the directory in which the file is located, #Gazer will ask you to provide #Gazer access to the appropriate directory.
