I can no longer upload my Power Point presentations and recorded lectures. Things were ok until last week but this week, no go. I'm getting a 404 error message when submitting the file from my PC.  I think I have run out of space. A couple of things I do which may be causing this: 

• I load my video lectures direct from my PC to weekly course module 
• I load my Power Point presentations the same as my video lectures. 

Questions:

Should the video lectures be moved to Studio or to YouTube then Studio?

Is it wrong or does it take up excessive space to load the Power Point presentations direct to modules? Is there another way? 

Thank you,
