SFTP and SCP are programs/protocols to login to another computer over a network to move files from one machine to another. They provide strong authentication and secure communication over insecure channels. They are intended as a replacement for FTP (File Transfer Protocal). FTP is a completely unencrypted way to transfer files. When using SFTP or SCP, all activity is encrypted, and this prevents others from intercepting your password or data while you work.

To download WinSCP, please click on the following link: http://winscp.sourceforge.net/eng/download.php

For instructions on how to use WinSCP, please refer to the DECS website using the following link: http://www.egr.msu.edu/decs/how-to/use-winscp.php

The directory for classes is /egr/sites/www.chems.msu.edu/htdocs/classes/<semester>/<course>/, where <semester> is the semester, e.g. f04, s05, u05, and <course> is the course number, e.g. 250.

Note that is is possible to view/set file permissions using WINSCP to make sure that the files belong to group che-web and that the files are world readable.
