  File Enumerator
  Submitted by



The following code lists all the files in a directory, and allows you to set a callback for each new file or directory that is found. The _directory_ parameter should be provided with a directory name plus wildcard (i.e. "/stuff/*.*"). Set recurse to true if you want to search subdirectories.

The zip file viewer built into the Developer Toolbox made use of the zlib library, as well as the zlibdll source additions.
