Client-Side ActionScript Language Reference

The following list summarizes how the user’s disk space choices interact with remote shared 
objects from a specified domain that request local persistence: 

■

If the user selects Never, objects are never saved locally, and all 

 

commands issued for the object return 

false

. 

■

If the user selects Unlimited (by moving the slider all the way to the right), objects are 
saved locally up to available disk space.

■

If the user selects None (by moving the slider all the way to the left), all 

 commands issued for the object return 

"pending"

 and cause 

Flash to ask the user if additional disk space can be allotted to make room for the object. 

■

If the user selects 10 KB, 100 KB, 1 MB, or 10 MB, objects are saved locally and 

 returns 

true

 if the object fits within the specified amount of 

space. If more space is needed, 

 returns 

"pending"

, and Flash 

asks the user if additional disk space can be allotted to make room for the object.

Additionally, if the user selects a value that is less than the amount of disk space currently 
being used for locally persistent data, Flash warns the user that any shared objects that have 
already been saved locally will be deleted.
