Hi Les. You may have missed the reply to you that I sent to the list.

I posted also to the KDE list to see if Konqueror's file manager would show 
file numbers including all files in subdirectories. The answer was yes, but 
in my FC2 with an older version of KDE this is not displayed, but in FC5, if 
you right click on for example my Sounds-Library directory, and go to 
properties, it does show a total for all files in the directory, including 
files in subdirectories. With my Sounds-Library that amounts to 17480 files.

Kevin Krammer at KDE also gave a CLI solution as below, and that works also.

$ find /path/to/folder -type f | wc -l

I did try ls -a, and ls -al, but both just give a subdirectory list, one with 
a bit more info than the other.

Thanks for the reply.
