auto naming exported file to specific path

When I export a file I want the file to be exported to the same folder in which my active file is. Also the exported file should have the same name
( plus Page no) , as the file from which I am exporting.

For example
1. If I am exporting page 2 of document D:\ August \Client.cdr
The file should be exported to D:\August\
If I am exporting page 3 of document E:\ Friends Club \ST\Brochure.cdr
The file should be exported to E:\ Friends Club \ST\


2 And the file name should be like ‘ Client P2.jpg ’ or 'Brochue P3.jpg'
ie. ‘File name +page name. Extension’

Can anyone help me with the script
