File Upload Widget

File Upload Widget

  
Has anybody worked with the "accept" keyword to filter types of files to be uploaded ?

As described in this document http://msdn.microsoft.com/en-us/library/ms533060.aspx
However it is not supported everywhere http://p2p.wrox.com/classic-asp-basics/16130-input-type-file-specify-file-type-path.html

I want to be able to have the possibility to only select XLSX files.
Hi Joop.

I've tried it, and it seems to work in Chrome, but not in IE... (Why am I not surprised?)
Anyway, to filter xlsx files I used the application/vnd.openxmlformats-officedocument.spreadsheetml.sheet mime type.
