@Ehsan Jahandarpour , an application must be on a billing plan - there are three to choose from: Springboard, Cloud9, Cloud99. You can manage your app’s billing plan on the Manage > Billing screen of Backendless console.

When the trial expires, you need to choose a billing plan so the app can continue to function. Selecting a function pack (like this one “10 GB o File Storage”) does not select a billing plan, but expands your file storage capacity.

Hi guys,My trial has ended and i would nee to use the files only, at least for now.If I buy the 5$/m package for my storage will they be accessible again. currently they are set to be seen publicly, but because of trial end all are restaicted
