[himansu_s_swain@xxxxxxxxx (Himansu Sekhar)]

Hi All,

      In my project, I have some perspectives..in some perspective I need 
to change view arrangement and then I am saving thoes custom perspective 
using eclipse's default Save Perspective As.. dialog.

I need to know the exact location and exact file name of thoes custom 
perspective.

Where thoes custom perspectives are stored ?

And how eclipse manages thoes perspectives during opening and saving ?

And what are the parameters eclipse takes to store thoes custom 
perspectives ?
