Why I need it is simple- I need to show/count how many "user" files are in the
folder, to the users. I'm migrating an Applescript based app to Cocoa.
I believe I neglected to mention that the folder I am looking at is on a
Windows server, so any native-ignoring of .DS files might not work. But as I
use the command, I can see that my count is "1" when really it should be "0"
but doing terminal ls -A reveals hidden files to me.
I think I might try getting every file name of the folder, and then removing
any file named ".DS_Store" or starts with ._ etc from the list, then counting
that revised list. I'm working in a controlled environment at my office and I
know these folders won't have more than say 100 items at a time, so time spent
in a loop isn't a big factor for me.
Thanks Kirk...
