Install to a different location

Hello,

I am sorry if this is the wrong place to ask this query I cannot find support anywhere else with this.

I want to install the game to a different folder for minecraft (locally). Installing the game on every network account will take up a lot of space on our servers and this will upset my network manager greatly.

Is there a way to change the default install location with out having to create a redirect as this will not work in a network set up?

I obviously understand that students will all share the same saves.

Thankyou,

Ross
