Hi!
Im using Exiftool from some time, and this tool helped me a lot in my work (as QA).
Today I have blocked/stopped/crashed on removing some xmp data which  -all:all/-xmp:all/GUI cannot delete :(
The data looks like :

<?xpacket begin="" id="xxxxxxxxxxxxxxxx"?>
<x:xmpmeta xmlns:x="adobe:ns:meta/" x:xmptk="Adobe XMP Core 5.6-c014 79.156821, 2014/08/29-03:07:50        ">

   xmp:MetadataDate="2017-07-21T11:01:50+08:00"
and so on..


Rest of xmp data is already deleted, or If i work on next file is removed with no problem, but always this keeps remaining. This problem don't occur on PSD files.
Any ideas how can I beat it?
Thanks for your time!

If you could send a sample file to me, I'll take a look (philharvey66 at gmail.com)

...where DIR is the name of a directory/folder containing the images.  On Mac/Linux/PowerShell, use single quotes (') instead of double quotes (") around arguments containing a dollar sign ($).

I got the sample.  This is a PDF-format AI file.

You should have seen this warning when you edited the file with ExifTool:

    Warning: [minor] ExifTool PDF edits are reversible. Deleted tags may be recovered!

ExifTool is removing the XMP from the document dictionary.  However, PDF edits are reversible, so the data is never actually deleted from the file.  The data may be removed permanently using a utility such as qpdf.  See point number 2 in the PDF tags documentation for details.
