PROBLEM:

No such luck.

If you know there is only one item in your file upload control, you can use Get item from collection for Index zero, storing the item in a variable of type file:

Alternatively, if your file upload control contains one OR MORE files, place Store a file inside a loop for each (with Data type: File) that processes the files in turn.
