Release the memory in my applet

[ordane]

In my project, I need to implement the file structure in the applet. I know that the memory should be released after the file deletion. Now I have several elementary files under the dedicated file. But how can I release the memory in my applet?

It depends on your implementation. You can just mark the file as deleted and return the appropriate error if someone tries to access it.
