windows explorer to be using asa smart tunnel

You should be able to open Windows Explorer, Tools, Map Network Drive and access your files. I do that through VPN tunnels all the time.

If you have difficulties:

1. Ping the IP address of the remote site to make sure you can see it.
2. Map the network driver by IP address of the remote site in case you have DNS issues.
3. Check firewall settings as firewalls can block connections.

are you referring to  VPN client or any connect VPN, because i am talking about web-VPN

and using smart tunnels.

I have not heard of smart tunnel. Any tunnel I have ever used is an encrypted VPN tunnel.

Please see the screen shot.
i have allowed RDP to use the smart tunnel but want windows explorer should be able to browse internal network

User experience :
loginto https://firewall external ip/
tunnel get auto started
minimize the internet explorer window
open RDP( mstsc.exe) loginto the internal desktop /server using windows application : no java no applet no active x

no need to install any application on client PC like cisco vpnclient or any connect software.

Please help i want windows explorer should be able to access the internal network.

The screen shot does not get any useful information.

For the internal network you wish to use, try the following:

NET USE Z: \\IP_of_internal_network\folder

What answer do you get?

no , it didn't work
i can not ping the internal host but when i use RDP i can loginto the internal devices

i have implemented ssl  web vpn and using smart tunnel

Make sure you have different subnets on each end.

Make sure the VPN (SSL) settings are the same on each end.

Check firewalls carefully on each end (allowing the IP ranges being used) because firewalls can block pings.

sorry its a web VPN : i am not assigning an ip address to users PC
they just have web interface via browser
