I just got a new power mac at work with OSX 10.5 leopard. I am a designer, and we have all our files on a server. The most important of which are quark documents. But any file that does not have a visible extension (.jpg .eps .psd etc...) that was created on another machine finder will not recognize nor will it let me open the file through the application that I know it goes to. It just tries to open it in terminal. HELP!! I saved a quark document from the new computer to the server and it did not have a visible extension but finder recognized it and let me open it. On my old machine I accessed this same file on the server and it only recognized it as a text file but did let me open it through quark. I'm kind of at a loss.
