Deleting files found by Diagnostic scan V4.2.2

[CraigPorter]

Just upgraded to 4.2.2 P4 and ran the Diagnostic program under Maintenance. The system came up with the following list of errors. Can these files be removed or should they be left in place?

Having done a quick check against a copy of the 4.2.2.zip file, none of those are in my copy so can be safely deleted.

Trevor,
Thank you for your help

Can these files be removed or should they be left in place?

Remember that most of these files are from plugins and if you delete them, they will no longer work.

Donald,
Thanks for the heads-up. I do not believe I have any plugins installed but I saved the files just in case something goes wrong.
