What are these hidden files in my home directory? [closed]
All of the files that you mentioned are part of Mac OS X already. Cups is to manage printers, netbeans is an IDE, drjava is for writing java applications, nbprofiler is to uncover memory leaks, and .profile can be used to set up aliases that act as shortcuts to commands. It is an optional file which tells the system which commands to run when the user whose profile file it is logs in. Hope this helped!
