Solid Explorer File Manager 2.0.3 (arm-v7a) (Android 4.1+)

This release does not have a Play Store Description, so we grabbed one from version 2.8.39:

Solid Explorer is a file management app inspired by the old school file commander applications. It will help you:
🗄️ Easily manage files in dual pane layout
🔐 Protect files with strong encryption
🖥️ Manage files on your cloud storage or NAS
☁️ Backup apps and files to any desired destination

Explore your device
Solid Explorer lets you navigate to files stored on your device and automatically organizes them into collections. You can view, delete, move, rename or share any files. It also allows you to quickly find the files you need through indexed search with filters.

Keep your files safe
Solid Explorer can protect selected files with strong AES encryption and put them in a secure folder, which contents are unreadable for other apps. The file manager will ask for password or fingerprint confirmation when you browse the folder. Even if you uninstall Solid Explorer, the files stay on your device and are still protected.

Analyze Storage
Although this file manager doesn’t feature a dedicated storage analyzer, you can find out which files take up most of space by going to folder properties of internal storage or SD card. You will find the information about the percentage of space each folder takes and the list of biggest files. You can also use search with a file size filter.

Organize remote files
Solid Explorer supports major network protocols and cloud providers to let you organize multiple remote file locations in one place. You can easily transfer files between cloud locations/servers just by dragging them from one panel to another.
