In my opinion, nothing comes close to Solid Explorer. I paid like R10 to unlock the pro version as an in-app purchase once ages ago. Simple, functional, supports everything (cloud drives, network drives etc).

Applications: App Backup & Restore
File managers like Astro and ES File Explorer does the normal APK back-up to your SD card. I would normally advise just re-installing applications from the market to be able to see updates, that said, having an old copy is sometimes useful when developers break functionality during an update.

ES File Explorer has become more aggressive with ads inside the app in the last couple of years. It does get annoying. However, you can pay a monthly subscription (starting $0.99 per month) to remove ads and unlock additional features like themes, SMB 2.0, and access hidden files.
very odd . never had any issue like that
