There is no limit to what you can do with it. You can view and edit anything on your SD card as well as in the Android system. ASTRO also comes with a Process Manager that will allow to shutdown pesky apps that go haywire or just to free up some memory from time to time. Personally I have always preferred to have icons w/ text or icons, rather than straight text for menu options and toolbars. Icons make it quicker to identify the option you are looking for by color/shape, rather than having to read lines of text to find the item you need. The UI is very clean and organized. Animations are fast & smooth and a nice UI enhancement. Probably the best file manager..
