Cannot access

WHENEVER I CLICK ON THE FOLDER OF THE NEXT NETWORK COMPUTER ON 'NETWORK' OF MY COMPUTER THEN IT SAYS 'windows cannot access to saurav-pc\photoshop" both the computers are mine.. how can i share that file between these two computers?

if i copy the folder to c:/users/public then i have access to it on other computer.. But i cannot open that folder if shared on d:/
