I meant to blog this a while ago. I found my lost file!
It was hiding in a second 'My Documents' that had been cloned on to the system where I had obviously saved it by mistake.
The Kingdom of God is like this. A man had all his other files accounted for, but had lost one. He hunted high and low for it, and then he found it. He said to his (desk) neighbours 'Truly it is time for rejoicing, for I thought this file was irretrievably lost, but I have found it! Come celebrate with me.'
So they had a cup of tea.
