File Walker

[JB]

Here is a link for a file and folder lister
that uses recursive.

http://lessons.runrev.com/m/4071/l/17080-files-and-folders-part-2

It appears recursive is limited to 400,000.

As for the File Walker link I tried it in one of
my folders that has a lot of files and subfolders
and it did not work for me but it did in other
folders.

If you get one that works please post it.

I cannot for the life of me find it in the Livecode Share site or the forums. I cannot search for “list files” or “find all files” because the forum search complains the words I am searching for are too simple! <GAAAHHH!>

In other words, it seems to be global to all instances of the iterations of the handler. I was under the distinct impression that each iteration had it’s own copies of a given variable because of the implicit scoping used by Livecode. Apparently I am mistaken.
