Hi, Douglas,That's not a bad idea, but would this not be a problem if the prefix (e.g., "Picture") were shared by another program, such as the system's screen-grabbing functionality? Also, if someone deliberately puts a file on the Desktop and names it "Picture 5", it could get overwritten if we don't check for it -- in which case we're back to square one, checking each time through our loop for a filename's existence. Unless I'm misunderstanding... which I have a tendency to do!
Cheers,
Andrew

Jean-Nicolas.Have you considered the notion of keeping your "counting data" in the user defaults? This would give you quick persistence, without having to calculate a value using the contents of a directory. Each time you create a new file, increment the counting data and re- store the new value in the user defaults. You could do a rollover check once your count gets to some arbitrary value (say 100).Note: This assumes that you want your count to be universal/system- wide. If you want it to be directory specific, you might implement the same scheme with tuples of directory paths and count values. Also, I assume that you always want to count up... meaning that if you have files picture 1, picture 2, and picture 4 in a directory, then the next file is "picture 5", not "picture 3"regards, douglas On Nov 23, 2008, at 1:45 PM, Jean-Nicolas Jolivet wrote:I would love to implement something like the default screenshot utility for OS X does when it names its pictures.. (i.e. Picture 1, Picture 2, Picture 3.. etc.)I was wondering if there's already something in place to do that? If not, I don't mind implementing it myself but I can't really think of a simple way to do it? Counting the files in a directory is not really a reliable way to do it (i.e. if you have Picture 2 and Picture 3 in a directory, your count is 2... try naming your new picture Picture 3 and it overwrites the existing Picture 3 ...)I'm fairly good with RegEx so it would be easy to parse filenames for numbers I guess but it seems a little overkill for such a trivial task... (especially since my app wouldn't use Regex for anything else so, I dont want to add a regex framework just for that)...Any ideas would be appreciated?
