See the
screenshots?
In the simplest linpus screens, you get a row of button-things across the top. Clicking on them changes the "page". I think your default set are called "internet" "work" "play" and so on, across the top of the screen.
These are called "tabs" [
better definition]. I see that the linpus tabs in the aspire one do not look much like card tabs.
Read the links I provided, look through the screenshots - some of them show you which screen to get the trash icon from. Explore the interface.
Probably you want settings > file manager ... though you could try rt-clicking the bottom panel (task bar thing) and adding a trash can to it.
