I traced an error last week down to an unlink that was failing since the script didn't have permission to delete a file. This surprised me, since the file had just been created by that same instance of that same script. It turned out there's a Security property that you can set on directories in windows 2000 to allow or disallow deletion of files in that directory.

So I thought I'd add some error checking into my script, and I found the Win32::FileSecurity module. It has a method, EnumerateRights, that shows all the security rights for a file/directory. It seems like exactly what I want, except that it doesn't show the "delete files within the folder" property that I'm looking for.

The property, on windows 2000, can be viewed by right-clicking the file, choosing Properties, clicking the Security tab, clicking Advanced, then clicking the View/Edit button. My guess is that the list of properties you see on this screen was expanded in windows 2000 and that win32::FileSecurity hasn't been updated since NT 4.

Does anyone know of another module or way to get at that property easily through perl? I found this page on microsoft's site that looks like what I need, but I'm not sure how I could use it from perl. Since some of win32::FileSecurity's constants match those listed on this microsoft page, I'm wondering if there's a way to peek at win32::FileSecurity's data and manually check for the other properties.
