We have a folder with 200,000 files on a network share. Customer won't allow us to separate the files into separate year folders which would solve the issue.

The issue is, when opening images from within this folder, it can take 2 or 3 minutes to actually load. If we load a PDF, it's instant. This happens even if you don't use file explorer, and instead use their CMS system which runs a shell command to open the file directly.

When the file is triggered to open, the Photos app opens, is blank white while it loads. While it loads, Task Manager shows "Shell Infrastructure Host" (sihost.exe) does something on the network at 10Mbps for the duration before the image loads.

The images are small, mostly around 100KB and the PDFS are the same. It's nothing to do with a bottleneck on the network.

Most people in the customers office have this issue, except a single PC which doesn't have the issue, there is nothing special about this PC.

What is "Shell Infrastructure Host" and is there a way we can disable this?
