How user can choose the latest file to be feed into SharePoint File Input?

[t_vuitran]

Hi everyone,

I have a workflow that I already built and plan to upload it into the server for user to run it from there. I used SharePoint File Input to read in the file followed by a Select tool as an example.

Is there a way for SharePoint File Input to always read in the latest modified file?

If not, can I use any tools in Interface to connect to SharePoint File Input so that on the server when user run this workflow, a window will pop up, and user can choose a file from a drop down list as their input file?

Thank you.

Is there a date in the file name that you could parse out? That's how I'm doing it
