Free online file conversion
A fairly common problem that crops up for both teachers and students, particularly in class presentations is the problem of incompatible files being used inadvertently. Zamzar may be the solution, you can convert files and videos for free at the site to a more compatible format. I did a test of a small document converting it to a .pdf, the process was quick - less than 2 minutes. I received the results by email. It could be a face saver for many students and ensure that presentations are completed on time.
