register a system event and look for

“applicationExit”

Additional information in page 54 of the APIReference

Couldn’t get it to work? could you send me some code to test?

I suspect it’s a me problem (it usually is) rather than something your end,

local function onSystemEvent( event )
if event.type == “applicationExit”
then
– save stuff to disk
os.remove( filePath )
os.remove( tagePath )
else
end
end
Runtime:addEventListener( “enterFrame”, onSystemEvent );

Shouldn’t it be:

Runtime:addEventListener ( “system”, onSystemEvent );

instead ? I might be wrong but that’s what I understand of the API reference. :wink: [import]uid: 1058 topic_id: 389 reply_id: 711[/import]

happylewie is right.

it should be Runtime:addEventListener ( “system”, onSystemEvent );
