I have multiple drives where I store information. A free program called "Everything" searches all drives... does it quickly... and gives reliable results.
Windows gets bogged down in their "indexing" and sometimes it takes FOREVER for it to display results. (And it only does one drive at a time.)
Everything
I tried to make a link to CNET's direct download (above). Maybe the link will work. If not, I just go to CNET and search their site for "Everything".
