Every member is allocated 2GB of storage space across their portfolio and projects combined.  Any file that you upload to your portfolio or projects where you are a collaborator will be counted toward this 2GB limit. This limit may be higher depending on the selection by your institution. One way to reduce the amount of space you use is to embed videos from Youtube or Vimeo, rather than uploading them. You can do this simply by copy/pasting the URL of the video when uploading video modules to your portfolio. You can also embed audio files from SoundCloud, following the same process.
