The high school building is closed on weekends. Sometimes a small section of the building is open for a specific purpose, such as a performance. Even in this case, students would not have access to their lockers or school computers.

Students can access the files on their computer accounts from home by using an option known as NetStorage, which you can learn about from this tutorial.

Another option is a method known as FTP (File Transfer Protocol). This requires a program like Smart FTP, which is available for free for personal, noncommercial use. The host name to use is: "www.arps.org" and the login name would be something like this: ".cruzj.CL10.stu.soa" (don't forget the dot at the beginning of the login name!) Your school login password is required.
