what is the difference between portable and usual windows versions in zip?

[metya]

I downloaded both versions and see no difference. But maybe there is?

The portable stores the data/configuration next to the executable. This means that if you unzip the portable version in another location, you get a completely new instance of the application. The non-portable version stores its data in AppData folder so if you download it again, you will get the previous data/configuration.
