Look at how I can't find a file that is clearly in the folder as I'm looking at it.
Folder: C:\Users\dasbest\Documents\Portable Apps\FL Studio 8\Plugins\VST-old
Filename: Prophet-V2.dll
Search pattern: prophet
I have rebuilt the search index, used the troubleshooter for fixing search and have restarted the windows search service. I'm using Windows 8.1 64 bit.
prophet*
