Big files take up lots of hard drive space, take forever to download and upload, and they can be difficult to send to people.
There's not much we can do about this though, it's just the nature of computers. But we can make the latter easier.
In this industry, large files are often thrown about. They could be hi-res images, videos, audio tracks, or sometimes even just really really long Word documents. But the biggest problem always arises when someone tries to send one in an email and hits their message size limit with one swift click.
All you need to do is drag and drop your file onto the screen, throw in an email address to send it to, and hit Transfer. All the hard work is done for you!
