Find specific subfolder in VB.NET? : So currently I have an area on a shared network containing subfolders of each product.

So right now my hierarchy of folders looks like this:

    Test Root Folder <--- This is my master folder
        Category 1
            Product 1 <--- this is the folder I'm trying to find
            Product 2
            Product 3
        Category 2
            Product 6
            Product 7
        Category 3
        Category 4
            Product 12

The product folders are always in this format "1234 - Product 1", Normally when I'm searching for it I know the beginning so I know the '1234' in this instance however I'm not sure what category it is in nor what the title 'Product 1' is only the 1234.

**How can I automate this search?**

Right now I've got a textbox1 for the '1234'
a button to click to enable a search
and a textbox2 for a hyperlink opening that subfolder so I can access the files inside.
