Excel 2010 :: Loop Through To Check For All Filenames In Folder And If Then?

getting a function working within Excel 2010. What I'm trying to do is to first look in a specific directory and loop through each foldername then check to see if the foldername exists in column B of my worksheet. If the foldername exists then check Column E of the same row for a specific value ("assigned") and then make sure column F of the same row has no picture inside the cell. If those three things exist (column B foldername and column E "assigned" and no picture in column F), then add a picture to column F of the same row as the foldername with a hyperlink to a filename of "notes.one" in that specific folder. Then just loop through each foldername in the specific directory until all foldernames have been checked.
