How to set the OpenFileDialog to open at 'My Computer'

StackOverflow https://stackoverflow.com/questions/1529406

Question

I wanted my OpenFileDialog to start at My Computer to show all available drives. You would assume you could set the InitialDirectory property to GetFolderPath(Environment.SpecialFolder.MyComputer), but this function returns "", which doesn't have the desired result.

Digging around on Google I found this solution - which works

dlg.InitialDirectory = "::{20D04FE0-3AEA-1069-A2D8-08002B30309D}"

Can anybody explain what this GUID actually is, and whether it will work across all versions of Windows? ie. How reliable is this approach?

Was it helpful?

It says it was used in Windows NT4/2000. I have Windows 7, and this GUID is still used for My Computer.
