APUS File Manager is a file management tool that stands out for its excellent presentation: it has a well-designed interface and is easy to use. When you open the application, the first thing you'll see is a list of the most recent files on your device: photos, documents, downloads, etc.
In the second tab (the one in the middle), you can filter all the files on your device by category. This way, you can easily find any image, song, or application that you have installed. You can also see how much space you're using on the device's memory.
In the third tab (the one all the way to the left), you can access a file viewer that's much better than the typical ones. You'll see a list of all the directories on your device: you can browse them, delete them, copy them, move them, etc. Basically, you can perform any of the actions that you would be able to do in a traditional file manager.
APUS File Manager is a good file management application that has a wide range of features and is also very easy to use. The only drawback (which probably annoys a lot of users) is that its interface has a fair amount of ads.
