We know shared assemblies are stored in the global
assembly cache (GAC)
Location of GAC
From .NET Framework 4
Location:C:\Windows\Microsoft.NET\assembly
In earlier versions of the .NET Framework
Location: C:\Windows\\assembly.
Assemblies are shared between all applications on
the machine, which is excellent for SharePoint
Versioning is easy because the GAC can hold multiple
versions of the same DLL without issues

A 32-bit system will only have the GAC_32 directory. A 64-bit system
will have both the directory GAC_32 and GAC_64. These directories contain
assemblies that are specific to 32-64 bit mode.

GAC_MSIL:
The GAC_MSIL cache contains assemblies that can be run in either 32-bit
or 64-bit mode. They don’t have any dependency.

1.0 and 2.0 both, then there will be two directories.
5.
Temp and Tmp
