Hmm. I have now encountered the same problem. As I wrote before, I had no difficulty with 100,000 files and directories 17 deep, but the same folders examined from their parent (the volume name) lead to a far higher depth count (should have been only 18)

The alternative might be some trigger into circularity, which is what happened with permissions.

Found it folks!


On OS X systems the folder //Network contains a reference to the local computer, which is where you started, so round you go again.

I made a specific adjustment at the beginning of the handler, thus:

   function walkDir dirPath
     if dirPath contains "//Network" then
       return empty
     end if
 -- etc as before

Running this worked across the entire root volume, returning over 230,000 files in a 24MB list (maxDepth 18 as expected), no problems.

The same circularity will equally affect an iterative routine, not only a recursive approach, so whatever you do you need to protect against the specific problem or simply not allow a user to walk from root. The point of this exercise was to confirm that stack size did not limit a recursive approach.

Note also WA's apparent problem with an X11 sub-folder, although aliases did not appear to have added any circularity in my testing. Any routine should also be tested specifically on a Linux or Windows platform if it will be deployed there. The testing code comprises displaying the current path every time you hit a new maxDepth.
