1. **\example\** (with the "exclude and subfolders" checked)
2. **\example\ (with the "exclude and subfolders" checked)
Number 2 is correct.
What's the difference?
I'm 90% sure Number 1 doesn't work. If you're pointing at a directory, you have to end with \, otherwise, it will appear to be a file. I also think that ** can only start an entry, but I'm not sure about that.
Which is correct from the above to exclude from every path the file "example.zip"?
Number 1 is correct. Number 2 will, I think, work fine, but Number 1 is more proper.
