Decide to work on your laptop instead of your desktop. Email yourself the file. Download. Work on it steadily for and hour and a half. Close the file and open your flash drive. Try to find the file to place in your flash drive. Great idea, except said file didn’t want to be found. A search using find revealed the older version (not even the one I’d downloaded an hour and a half ago). And it wasn’t to be found in the temp files either. Panic. Breathing exercises. Swearing. More breathing exercises
After much swearing, I did finally find it. Hallelujah! Now it is saved to my flash drive. And emailed to myself just to be safe. I don’t trust computers. Rightly so apparently.
