What do these blue arrows pointing at each other mean on this file icon? Never seen this before.
@Vanitas it was compressed to save disk space
@Mandypar Yup, remember that now that I know what's going on. Hadn't seen it for a while. And it's cool to stay compressed; data was written to the file for archive purposes anyway.
@Vanitas you can right-click, go into properties and change to stop it being compressed I think if that is important to you.
