[Samba] execute external commande : unrar

[taiky taiky]

hello
sorry for my poor english.....!!!!

i would like to know if it's possible to execute a exernal commande...

i explain...:

In windows , i have 3 network drives shared by samba....
So when i have a .rar in these directory, it's spend a long time to
decompress it from the windows interface..
I  would like to execute the 'unrar e myfile.rar' on the file on the samba
server from my windows laptop...

Can i  do this...? if Yes how can i do this...


THANK YOU VERY MUCH
