Using PHP 5.2.1, MS Server 2003 Hi, hoping someone who understands PHP can give me a hand with this. When the webmail application I'm using (squirrelmail) executes the following line in the php script: unlink($attachment_dir . $temp_file); I get this error: Warning: unlink(D:/SMData/Attachments/d8a356be315e72d1fae066fd61cb5a66) [function.unlink]: Permission denied in D:\xampp\htdocs\mail\plugins\abook_import_export\address_book_import.php on line 216 The webserver process/user has full access to and ownership of the D:\SMData\Attachments directory Basically, it can't delete the files that the script creates in that folder. There are no errors in the php error.log What other permissions could it be referring to? Thanks
