Do store documents that you create on your H: drive. Be sure to create a folder for your files.
Do backup your files to a removable media. This will also allow you to share data and large files with team members.
Don't save files to your desktop. This may eventually prevent you from logging out and cause loss of data.
Don't save files to H:profile or any folder with the word "profile". This folder is automated by the operating system and can be reconstructed or deleted at any time.
Don't save files to the local hard drive (usually C: or D:) in the labs or class rooms. These drives are regularly reconstructed and overwritten. In addition, when you log on to a different computer, your files will not be available.
