Creating parts with movable schematic elements

I started my Win10 and just renamed the folder where I had saved the sketch the previous night.
I then renamed the sketch which was still in the same (newly named) folder.
I had nothing else running at the time. This was the very first thing I done after boot up.
When I tried to open the newly named sketch, it gave me an error message which I did not record.although I believe it may have been this:
.fzz': zip.open(): %d
I tried renaming the folder and sketch to no avail.
I wonder if my ridiculous folder-naming convention could have played a part..?
