File upload pre-validation

Lapointe

Hi @all
Is there a way to validate extension, size and more before starting upload.
In fact, after many time of upload process, we can get the message 'size excedeed' or ext no allowed...
perhaps a way to verify these std points before launch upload ?

Thanks
Bob

This also has an example for checking file size.
