The method that I posted gives you several options. You don't have to search subfolders.
It finds all files by the y="*" but you can filter for other file names like "*.doc" if that is what you wanted.
So, the last modification would be the path that you pass to the function. Not sure how C30's 0.83 would be part of path name though.
Since you are not checking subfolder paths, a simple Dir() Loop can be used to get your files. This may be the best route for you anyway. However, more example data would be needed for me to determine your needs a bit better.
e.g.
1. C30=4
2. Clicking the button does this.
a. Deletes all data on Sheet "Silo 1".
b. Puts hyperlinks to all files in "Silo 1"'s Column A1 and down from path: x:\templates\4\
As you can see, I don't know what you want specifically.
