X-plore allows you to see inside of your Android device. And also outside.

This is a dual-pane explorer, there are two folders shown at same time, and common operation such as copying files are done from one pane to another.
And X-plore shows folder hierarchy in a tree view for clear orientation and fast switching to other location.

You may explore internals of the device, and if you're power user and have your device rooted, you can make changes to system data - backup files, remove unwanted applications, etc.

If you're standard user, you may choose to hide internal memory from view and be sure not to mess with system.
You can comfortably see contents of mass memories on your device, or possibly attached USB memory stick.

Simple app manager allows to see, run, copy, share, uninstall and further explore installed applications.

SQLite database viewer
X-plore can show SQLite database files (those with .db extension) as expandable list of tables, each table containing list of rows and columns with database entries.

Main interaction is done by touch screen, clicking on folders or files to open files, or long-click to open context menu which contains options which can be done on particular clicked item, or multiple selected items.
