Hi, I saw some posts on StackOverflow about validating files using JavaScript's files api (it looks fairly new so may not be suitable for projects which need to support old browsers):
https://www.google.co.uk/url?sa=t&source=web&rct=j&ei=omB3Vb_MKKi07QbRvoDYBQ&url=http://stackoverflow.com/questions/3717793/javascript-file-upload-size-validation&ved=0CB0QFjAA&usg=AFQjCNGck_7qB8b7VzFExHQM72vzF6JxZA&sig2=XgAbDcP-E8-daXfAyP0tEg Some time ago I implemented a client side twitter validator to check the length of text field values (it gets a bit complicated because links count as fewer characters etc). I can have a go at doing the same for the fileuploader and can put whatever I make up on github somewhere. It won't work on old browsers as per: https://www.google.co.uk/url?sa=t&source=web&rct=j&ei=Y2F3Vbf0IIet7AarkoLgBA&url=http://caniuse.com/fileapi&ved=0CB0QFjAA&usg=AFQjCNEufMjex_NEpHKkWV7k-pakFWDNJQ&sig2=-hTtFzGroBPZc9w0v1bGIA I'm a bit surprised that this doesn't exist, I thought it would and so I expected that I was doing something horribly wrong. I'll come back when I have it working as it may help others.
