Hello Alteryx community,
I currently have a workflow that works as expected when the data is available for the day. The workflow takes todays file from a folder and copies them into another one. Here's a picture of the workflow:

My problem comes up when the data isn't available for every file. In such a case, I would like to keep the old data inside the new folder for the files where the data isn't available.
To help illustrate my situation, here's an example. So, the workflow last ran on the 23rd and since all data from every files was available, I have these files in the folder:

Now, today, not all data was available for every file, and with my current workflow, I end up with these files in folder:

As you can see, there are empty files. The results I would like to end up with is something like this:

Any help or pointers would be greatly appreciated.
Thank you,
