Configuration files
Application has several configuration files:
-  Portable.ini -- flag-file which sets portable mode;
 -  Viewer.ini -- main configuration file;
 -  ViewerHistory.ini -- various histories: window position, search strings etc;
 -  lsplugin.ini -- configuration of some Lister plugins.
 
Config files are searched in the following locations:
-  Location specified in the command line "/Ini=" parameter;
 -  UV folder, if Portable.ini file exists there;
 -  Location stored in the registry under "HKEY_CURRENT_USER\Software\UniversalViewer";
 -  Location stored in the registry under "HKEY_LOCAL_MACHINE\Software\UniversalViewer";
 -  Lowest precedence: "%AppData%\ATViewer" folder.
 
To be sure that application is made portable,
you need to create Portable.ini file in the app folder.
