Hi ​@Fernanda Barbosa  Welcome to the Box Community! We’re only able to provide assistance in English. Thanks for your patience.
 

From the translation, I understand that you need assistance regarding missing files. Apologies for the inconvenience. This may be related to a known issue: Customers may have issues with Uploads, Downloads, and accessing the All Files page.
