Don't be frightened by the length of the tutorial, it's
as simple as A,B,C
With this tutorial you can:
*transfer files at speeds much higher than bluetooth
and pretty close to USB between Phone and PC
*Play Audio, Videos and read documents stored on
your PC directly on your phone. This is super cool and
useful if your phone has small storage space.
* You don't have to be close to ur PC, you can be in the
toilet and still do your thing (That's if una toilet no dey
inside bush o lol..)
And some cool advantages
NEEDED:
1. Accessible WIFI network or LAN. OR Portable hotspot
on your device.
(Note: you don't need to have internet Plan or Internet
access)
2. ES file explorer. This is free from playstore. I
uploaded a copy too. You may use other File Managers
3. Windows PC xp/vista/7/8 with administarative rights
PROCEDURE 1
## Find IP Address or make static IP[optional]
* Put on your Portable hotspot from your device and
connect your PC
* Enable " file sharing and turn on device" if prompted
(I'm using windows or right click the connection and
enable it.
* Go to network connections by Start Run (or press
Windows key + R), Type "ncpa.cpl" (without quotes)
and press enter
* Double click on the Wireless or LAN connection
depending on what you're using
* Click on details and here note down
a. IPv4 Address.
b. IPv4 Subnet Mask
c. Default Gateway
d. DNS Server.
OR
## Find System Name by
Right my computer, then click properties, below you'll
see your System Name.
NOTE: System name is not the same as User name.
If you want to use IP address method is better to use
static IP address, in this case the IP won't be changed
by the Router.
To set static IP address:
a. Go to Network Connections
b. Double click on the connection
c. Click on properties
d. Double click on - Internet Protocol Version 4 (TCP/
IPv4) and fill up the IP address as you have noted them
down above.
e. Click on OK for all dialogue boxes.

Install ES file Explorer
PROCEDURE 3
1. Windows Vista/7/8 PC:
i. Share the drives or folder you want to access by
a. Right click on the folder you want to share

it and you will see all your shared files/folder of the
system there.
2. Windows XP PC
i. Firstly you will need to enable Guest account by
going to Control Panel – User Accounts – Guest Account

there is no other way I found to access the files in
Windows XP in Android device with actual user name
and password.

a. Right click on the folder you want to share
b. Go to the sharing tab

PC username and Password)
vii. Give a name under "Display as" for easy
identification
viii. Tap on OK.
ix.Now you will see an laptop with globe icon. Tap on
it and you will see all your shared files/folder of the
system there.
Useful tips:
1: You can increase the transfer speed by moving near
to the router. The closer you are to the router the
higher speed you gain.
2: You can even make shortcut of the folder in the
network and place them on the home screen of the app.
Do to that on ES File Explorer simply long press on the
folder and choose "Add to server list".
Notes:
1: Please note that no internet connection is required to
make this possible. Everything is done through the
local network. Take out the idea from your mind that
Wi-Fi is only for internet.
2: There are various other apps like KiesAir, AirDroid.
But that will require you to be near the PC and access
the files through a WebUI. But the guide which I have
laid out here works from PC to device directly. You can
sit at your living room, kitchen or bedroom or where
you like within the Wi-Fi network and you are good to
go.

PS. You could turn off your data connection it'll. still work great.

I am glad you've shared this method to accessing files on an android device without using Bluetooth or usb. I will use this in MyPCFile software, and I hope it will prove to be valuable for me.
