Sharepoint On-Prem: Get File Properties returns ALL files in site

[ericonline]

Hello,

I'm trying to get files from an On_prem sharepoint site where created date is less than today - 3 days. 

Observations: 

1. The Library Name must be URL Encoded

  - Can't use "/Shared Documents" like I can with Sharepoint Online

  - Have to use "Shared%20Documents" (that was fun to figure out)

2. Even though Limit Entries to Folder is set to a folder within Shared Documents, this action still returns ALL FILES IN THE SITE that meet the Filter criteria (Created < Today -3)

**How do I get this action to only return files in the given subfolder?**

Do I really need to use the Filter Array hack described here?
