[WP 8.1] How to access NAS?

[Windows Central Question]

So, I have HTC One M8 for Windows with WP 8.1
If there is no particular app from manufacturer for accessing NAS (Network Attached Storage), how can I access it?
Many third party apps and built-in app only let me access local storage and SD card.

For example, ES File Explorer on Android lets you to add LAN storage if you put IP address and log in information.
But WP file explorers or file manager apps doesn't seem to have such an option (I only see Local, Cloud, and FTP)

Does anyone have a suggestion?

I have ASUS RT-N66U router and Seagate 2-Bay NAS.

Try Metro File Manager. Or search for SMB in the store.
