Setting system default explorer bug

[zengqu]

When I use explorer++.exe to replace the default file explorer of the system, I open the folder where the cpp file is located in visual studio, and cannot locate the specific cpp file，and sometimes it wast a long time to open the folder.

I found the problem. it can open the desktop folder, but cannot locate the items on the desktop folder. In fact, as long as the files in the user directory such as "C:\Users\zengqu" or the files under the subfolders cannot be located .
