Thank You for your help! Unfortunatly I can't send You any of theese files, since they have been created on Smart Office 2 on Ipad and now the app says it's impossibile to unload the document (in Italian: impossibile caricare il documento). Therefore I can't do anything: I cannot open, edit, share, print any of them. Most of them are .docx files, I added some images and they are from 2 to 20 Mb. But in Timeline I can see the document has still a content!
