manipulate explorer.exe

Question

Hello,
Our company uses a small tool written in c# where we can enter a 5 digit project number and it redirects you to our project disk on the network. It saves the users some time searching for their projects.

It is possible to manipulate explorer.exe so when a 5 digit project number is entered in the address bar, the explorer.exe will do the same? I think a .NET application should be able to do it, but I don't know how.

Any ideas?
