@todd_r if you upload a file other than in the DWC instance you are viewing (for example, using direct upload from a slicer, or using a difference instance of DWC) then you will need to press the Refresh button to see the new file(s). When you upload in DWC, that instance of DWC should show the new file immediately, although it may of course be off the page depending on what file sort option you have selected.
