Spotlight does search other drives "on default", if I understand "on default" correctly. I have a couple Firewire drives that will be searched by Spotlight when they are connected, but not searched when unconnected. Spotlight finds information on these drives exactly the same as it finds information on the builtin drives. I also have all my internal drives partitioned, and Spotlight finds information on those volumes just fine. If you have a situation where Spotlight does not search a drive, you will have to provide details of the drive and its Spotlight status (e.g. is it excluded in the Privacy list) to explain what you mean by "not searching other drives on default".

There is a big difference between using Spotlight and using the 'find' command. Before anyone can reasonably reply with ideas regarding the use of 'find', you will first have to explain what files you're searching for, where you're searching for them (networked or not), what your search criteria are, and why you think 'find' will work better at this than Spotlight.

If you save the output of 'find' to an array, it can become stale (i.e. wrong) if the user makes any changes to the filenames or the locations of files listed in the array. Without knowing anything about what you're trying to find or why, or the lifetime of the results, it's impossible to advise about the efficacy of storing the output in an array.

Since 'find' delivers results incrementally, as it finds matching items, that seems more like an iterator or enumerator model to me. You could collect all the results into an array, by waiting for 'find' to t...

erminate, but if 'find' produces a lot of output before the rest of your program can start processing it, you might consume a lot of memory for no good reason.
