Hello,
How do I validate files before they are uploaded. i.e. if I want to only allow files that have the word 'banana' somewhere in the filename, how do I check that before all the files are uploaded?
If the validation fails, how do I then cancel the upload? If multiple files are selected, and only one fails validation, can I just abort the upload of that one file?
