Hey, I've been using Ubuntu for about a week, It works well But there is one thing that I found to be annoying - these are the differences between file browser (Nautilus) and the select file menu. Windows allows me to: rename, delete, copy, past in the file select menu, however Ubuntu does not.

Then you have to open the whole file browser and look for this file just to change the name, because otherwise you will get an error like: 'JPH' format isn't supported.
there are a two picture to show the differences:
