How to upload files, suitable restrictions in Drupal using plupload?
The bottom line: use the plupload library (integrated of the same module). When setting the limit to 5MB here admin/config/media/file-settings stops to upload files more than 5 MB (which is logical).
Problem: when I throw a stack of files, even if only one does not fit - not downloaded all files.
The crux of the matter: how to make all files that match in size, is loaded, and the rest not?
