Copying dll from GAC

Recently i have   faced one problem that is copying one of the dll from GAC.
.But we can not copy directly from GAC .Finally i have achevied this way .

Goto    Start  -->Command prompt

Type in  Command Prompt --> subst  Z: c:\Windows\Assembly

Click on enter

Note: subst  is a  command which  creates a virtual drive


The abouve syntax creates one virtual drive "Z"  and copy all dlls from GAC

-->Now you can go to Z: drive and copy your rerquired dll
