Count number of files in directory and subdirectory

I'm trying to count the number of files in a directory and all the sub directories. The command "find . -type f | wc -l " worked in a directory with a few files and sub-directories but it is not working in a directory with lots of sub-directories and files. It just comes back in a few seconds showing nothing. The slice is 100% full. Not sure if that's playing a factor.

Any other good way to count?

du -k  doesn't get the hidden files and it includes the directories. I just want a file count

"find /blah -type f " doesn't work any better than "cd /blah; find . -type f" It returns files in the current directory but not sub-directories. I didn't realize that at first because there were no files in the the current directory until I just put one there. It see that and the quits.

I did discover one other factor that may be important. The directory (and sub-dirs) are on a NFS mount. The mount is a equalogic san. Does find work different on NFS mounts?

That explains it... all Unix filesystems and windows filesystems have a . & .. entry as a link to self & parent directory.
Non unix native filesystems (f.e. ODS-2, ODS-5 on OpenVMS, FAT top level directory, ISO-9660 (CD/DVD format) dont have these... That would not be a problem if find actualy checked for those.
To speadup operations it counts the entries in directory and substract 2. If there are less then 2 entries in a directory it will asumme the directory is empty and that's it.

The RR- extenstions supply a fake . & .. but without them the ISO-9660 fs doesn't have those . & .. references.

ls has a likewise quirk. To prevent unneeded printing any file starting with . (. & ..) is suppressed (unless -a is given).
this had the side effect that any file starting with . is not printed in a regular ls command.  Hence the 'hidden' files in Unix.

The fact that the directory is on CD is a mayor factor in getting the solution to this question.
