1. Testing Write Access on Windows

What's a good way to test for write access to a directory on Windows? Is there a flag available somewhere, or do I need to attempt to write a file and gauge results based on that?

include std/filesys.e 
sequence c = dir( `C:\` ) 
for i = 1 to length( c ) do 
	if find( 'd', c[i][D_ATTRIBUTES] ) then 
		printf(1, "%s: %s\n", { c[i][D_NAME], c[i][D_ATTRIBUTES] }) 
	end if 
end for 

But that's only going to tell you if the directory is marked "Read only". Other file security restrictions could still apply, making the directory effectively read-only. You may be able to use the PrivilegeCheck function to check your permissions, but I am not entirely sure how to do that. Another approach would be to pull the ACL from the directory with GetSecurityInfo and look for Write and/or Modify rights for your user or group.

Or, you know, just test by trying to write a file.
