29.6. Working with Size Constraints

Ultimately, the user has control over whether your program can store data locally, and how much. Therefore, technically you can't rely on local shared objects for your application to work correctly. However, the vast majority of users have local shared objects enabled, and in reality, you can make this a requirement without shutting out more than a user or two. Your power users are far more likely to disable Flash Player entirely than specifically limit shared object use. The same limitations hold true for browser cookies, and there are a great number of web applications that require cookies. In fact, local shared objects have an advantage here because you have the ability to query the user for more space when you need it.

29.6.1. User Settings

You, and any Flash Player user, can control Flash Player's policies on local storage by accessing the Flash Player Settings Manager. The Settings Manager is an embedded control panel that you can find by accessing http://adobe.com/go/settingsmanager.
