If you navigate to %windir%\assembly , you can not see the default folder structure of GAC.
You can map a drive directly to your GAC and then you’ll be able to see the actual directory structure.
Open start menu > Run and type
subst z: %windir%\assembly\gac
There is one more alternate way (not preferred since you have to deal with registry)
- Open Regedit, browse to HKLM\Software\Microsoft\Fusion.
- Add a REG_DWORD value named ‘DisableCacheViewer’ with value 1
- Navigate in Explorer C:\WINDOWS\assembly\GAC_MSIL\
