You could also say that as more apps store info in a directory, the overhead associated with that directory increases. So what? > What happens when you remove an > application from the system?

What happens to the shared libraries, preference files, rc files, and documentation files when you remove an app from your system? They still sit there. This is one of the reasons I advocate a Linux Registry. Anyways, EA's won't make this problem any worse than it already is. > Is there a way to register the EA information in an application > associated and/or user associated space, such that this info can be > removed easily with the user or the application and such that the actual > files do not need to be accessed in order to do so? Yeah - build a systemwide Registry. > Additionally, how does one transfer a file and its EA's to another > system?

Yes - you carry all the info. Remember, though, that EA's are usually *very* small - less than 10k if done correctly. System-specific data has no place in EA's - only application-specific and user-specific data. -- Adam Megacz <kalessin@netcom.com> Website ftp://ftp.netcom.com/pub/ka/kalessin/adam.html Linux - OS/2
