Create a local command in BatchPatch (‘Actions > Execute local process/command > Create/modify local commands‘) with the following syntax:
cmd.exe /c start \\$computer\c$
or
cmd.exe /c start \\$computer\SomeOtherFolder
You will then see your local command under ‘Actions > Execute local process/command > Execute saved local command‘. You can also add a toolstrip button with ‘Tools > Customize visible toolstrip buttons‘. Just scroll to the bottom of the ‘Customize Toolstrip’ window and check the box next to the local command that you created.
