I don\'t see an option in the plupload API docs on restricting the number of files uploaded, to any number, even 1.
Doc fail? or Feature fail? If it doesn\'t exist I\'ll
Remove unnecessary files directly before uploading:
$('uploadfiles').onclick = function() { while (uploader.files.length > 1) { uploader.removeFile(uploader.files[0]); } uploader.start(); return false; };
