As title said, an excellent software. I installed in my system as a backup once ... expires. But here are some personal opinions. I don't like the big buttons, which look like a big stone on the top, especially those two grey ones. I think maybe more and smaller buttons should be put in toolbar. The other thing is about easy to use. I spent nearly one hour to figure out how to zip a file, because I can't see any file in the inbuilt browser. If you count how many clicks you need to finish a compression, you will know why I didn't mark the ease of use excellent.

Hello. Thank you for your comment. You can set smaller icons with a right-click on the toolbar: you will see a popup menu that will let you customize the toolbar layout.
In order to ZIP a file, you can simply right-click on the file you need to ZIP (you will see the context menu options) or you can use the ZG main application: click "New" to create a new ZIP file and program will show you the file compression dialog.
