This release does not have a Play Store Description, so we grabbed one from version 2.4.0:

New feature!
Now you can protect your files and folders with a password. If your device has a fingerprint sensor you can use it to open encrypted files without a need to provide the password. The same applies for cloud storages, which can now be accessed with the fingerprint as well.

Apart from the ability to manage files in almost every location, it also gives you many customization options, such as themes, icon sets and color schemes. You can freely adjust the interface to match your taste. Dual pane file browsing with drag and drop greatly increases your productivity.

Solid Explorer is a great cloud file manager, because it provides you a wide support for cloud storages including Dropbox, Box, Google Drive, OneDrive, Mega and Owncloud. This file manager can also connect to your Windows PC and many remote servers working with FTP, SFTP and WebDav. By the way, you will appreciate the ability to create or extract most commonly used archive formats, such as ZIP, RAR and 7ZIP.
Maybe you're tired of ugly looking root explorer apps? This file manager will meet your needs. It features a root explorer with ability to change system level file properties. You don't need to remember about mounting file systems as read/write. Solid Explorer will do it for you automatically.

Solid Explorer is also a great file manager for viewing your media. It can arrange your photos, videos and music in one place for easy and quick access. It has a built in music player and image viewer, which even allow you to play remote content stored for example on your PC, Dropbox, OneDrive or Google Drive. The most cool thing is that the content can be casted to your Chromecast.

Just give it a try! You will not be disappointed.
