I want to open the File Explorer so it highlights a specific file (or shows the results of a search.)

I can open the FE easily using:

Code:
System.Diagnostics.Process.Start("explorer.exe", My.Computer.FileSystem.GetParentPath(myFile))
...which opens the FE at a specific location (the "System.Diagnostics." prefix opens a new Explorer window in case the FE is already running.)

But I don't want to show ALL of the contents at that location, just files ending in ".bkp" (adding it to the path doesn't work.)

Is there an easy way to do this? (If the solution requires more than 3 lines of code, don't bother. it's not that important.)

TIA
