Eclipse CVS copying file with right-cliking

I use eclipse Ganeymade with CVS ,when i compare the code with repository ,eclipse take me to new perspective ,in that perspective if i tried to copy file(right click and select copy) it not allow me to copy.What i I did is Just to other perspective like J2EE then copy the file

is there any way to do the same?

It's not taking me to a new perspective, and I can copy/paste the content of both files. Which perspective is it taking you to ? Which menu are you using to compare files ?

when I synchronize ,it take me to "Synchronize" perspective but when i try to copy more than one file ,it not allow to copy.

My intention here is in synchronize perspective i want to copy more than one file

So you are synchronizing, not comparing. Synchronizing takes you to the Team Synchronizing view, which makes sense. Then you see a bunch of file which need to be synchronized. Then, what do you want to do exactly ? I'm not sure I understand what you mean be "copy".

sorry , i do not know whether i am explaining correct way or not ,

In the Team Synchronizing view,i want to select multiple files (ex :four java files) and right click on the files and in the menu select copy

I see. Unfortunately, that view was not made to copy files. It's just a view showing differences between your local project and the repository content, and synchronize their content.

Can't you copy the files from another perspective (Java/J2EE...) before synchronizing ?
