Android to Android file explorer using wifi direct Is there a way to access files of an android device from another android device using wi-fi? I need like a file explorer.
Generally any good file explorer with FTP, SFTP, WebDav, SMB/CIFS capabilities can handle this task with ease or other wi-fi file sharing applications.

You can even browse through PlayStore to get the right one e.g Solid explorer, Total commander etc.

For starters you can run through Izzy's list of Filetransfer between two Android devices

For purposes of explanation I chose ES Explorer, it  has a lot of functions including remote browser:

You can use the following proceedure to access files in another device:


Install ES explorer in both devices if you haven't already done so.
Switch on portable hotspot and allow both devices to connect.
Using phone A, open ES explorer and go to remote manager and turn on,
see below

Copy the server details from phone A, you will need them in phone B

Using phone B open ES explorer and navigate to Network → FTP

Add a new server using the details you previously copied:




When setup is completed you can now browse the files of phone A from
phone B




See screens from both devices:
