Total Commander is the Android version of the same file manager for Windows and offers a series of similar benefits to those of its version for desktop operating systems.
That is to say, through the application you can move, copy and paste entire directories and subdirectories with ease. Create new folders or change the name of already existing folders, and of course delete files or folders. You have to be careful when carrying out this last action because you won't have a Recycle Bin.
More options of this Android version can be found when working with compressed files that you can open with ease and even create new ones. Independently, if a file is in .ZIP or .RAR, you will have no problems when seeing its contents.
Even more interesting than the before mentioned tools is the possibility to put a widget on the desktop with access to an FTP client, or have an internal text editor to work with without the need to resort to other applications.
Total Commander is quite a complete tool to manage files that, in spite of having an unattractive to ugly interface, offers a number of very high benefits. Furthermore, as ugly as its interface is, it's also as practical.
