I would like to ask if it possible to access the file being uploaded to alfresco without being log in to alfresco or share, and where does the file being stored so that i can access it barely using other structure like samba, thanks in advance
You will need to enable CIFS on your Alfresco server. Once you have done that, files will be available over the network. When you look at the details of a file, you will see several (iconic) links near the top that provide the access path to the file. One of them is for CIFS, and one for WebDAV, as well as some other paths.
