- ES File Explorer
What it is:
Amazingly, it’s probably the most popular file explorer app out there. That’s because it used to be really, really good – five years ago.
Why it’s bad:
The free version has been pumped full of bloatware and ad-ware, and it endlessly nags you to download additional apps via non-disable-able notification bar pop-ups.
What you should use instead:
There are loads to choose from. If you want an open-source offering turn to OI File Manager; if you’re more concerned with design try out FX File Explorer; or if customization is your thing, you can look to Total Commander.
