GAC folder in Windows

When we go the default GAC folder in Windows located at : "C:\WINNT\assembly" we see the dlls that are registered in the GAC. But what if we have different versions of the same DLL registered in the GAC? How can a single Windows folder allow 2 files with the same name to exist?

To understand this, go to the DOS prompt and navigate to "C:\WINNT\assembly". Do a 'dir' command and see the contents. There would be a 'GAC' folder and inside the folder, there is a folder for each Assembly. Each assembly folder has a folder for each version. Inside this version folder there is the actual DLL. Try this out :)
