Subj : File deleting & attributes

I'm working on a JavaScript script for Synchronet that involves extracting an
archive into a temporary directory, and then it will recursively delete the
temporary directory when it's done.
My BBS is running in Windows 2000, and it looks like if one of the extracted
files has the read-only attribute set, file_remove() doesn't remove it.  I then
started to look into how file attributes are represented in Synchronet's
JavaScript model and if it's possible to change them.  I noticed that the File
class has a property called 'attributes', and there's also a function called
file_attrib(), which will give you a file's attributes.  The attributes are
represented by a number, but the docs don't seem to say what that number means
or if there are any variables anywhere that represent different file
attributes.  I checked sbbsdefs.js and didn't see any mention of file attribute
definitions in there.

So, my questions are:
1. Is it possible to delete a file regardless of its attributes?  And if so,
how?
2. For File's attribute property and file_attrib()'s return value, what are the
attribute values that it can be checked against (or more precisely, where can I
find the list of attributes)?
3. If you wanted to change a file's attributes, can that be done by opening it
with the File class, changing its attributes property, and saving the file?
