The error is "There was an error uploading the file, please try again!".. Which technically would indicate a problem copying the file, though I can't see why (the smaller files work fine, and the disk isn't full). Here's the html form that submits the file: [code] <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <link rel="stylesheet" type="text/css" href="../pk8.css"> <link rel="icon" href="favicon.ico" type="image/x-icon"> <link rel="shortcut icon" href="favicon.ico" type="image/x-icon"> <title>Form Title</title> </head> <body> <form enctype="multipart/form-data" action="ulf.php" method="POST"> <input type="hidden" name="MAX_FILE_SIZE" value="70000" /> Choose a file to upload: <input name="uploadedfile" type="file" /><br /> <input type="submit" value="Upload File" /> </form> </body> </html> [/code] And I see my own problem... And it's embarassing. However, I hate it when I google, see what I'm looking for in a forum, then someone just posts "I found and fixed the problem" and never posts the answer... So, for posterity, here goes: It's in the MAX_FILE_SIZE form element within the HTML. How embarassing. I cut and pasted an example form after my headers to get started, and when things went awry I never looked there - just at the PHP and server config (which I thought was correct, and it turns out, it is correct). I'm a putz ::). Ok, maybe not a putz, but I can't believe I missed something so obvious. Thanks a bunch for pointing me in the right direction!! Tim
