About the expiration features, I read that;
"avoid using … For portable publications, you should forbid the entire access or use Security Profiles to partially lock your publication.
But, I don’t understand how to do it by using “Security Profiles”…
Could someone can let me know the steps for setting expiry date with “Security Profiles”?
A portable publication will never write data to the computer where it runs, so it stores data on the USB disk, that is the .license file. So yes, the user can reset his trial period by deleting the .license file. However, in that case, the license info is deleted too and the ebook returns to the Trial state.
Generally, by using expiration, you let the end user access the full publication during some time. Since there is a possibility for a skilled user to reset the trial period for a portable publication, we recommend you another approach: offer a crippled down version of your publication to trial users, and the full one to your registered users.

I have a portable application which runs as expected on a USB drive, saving data to “myprogram.userpref”. It will also run from a CD and apparently stores the same data somewhere on the users computer. Where does it put it?
