if sub.include?(“html”)  
path = File.join("/ACMServer\_exe/ChatHistory",f,sub\_folder\_name,sub)  
@file\_path \<\< path  
@found\_folder \<\< sub\_folder\_name  
@chat\_date \<\< f  
end

The above code has to be used in my controller repeatively in the same  
function.  
like below  
if something  
if sub.include?(“html”)  
path = File.join("/ACMServer\_exe/ChatHistory",f,sub\_folder\_name,sub)  
@file\_path \<\< path  
@found\_folder \<\< sub\_folder\_name  
@chat\_date \<\< f  
end  
elsif  
if sub.include?(“html”)  
path = File.join("/ACMServer\_exe/ChatHistory",f,sub\_folder\_name,sub)  
@file\_path \<\< path  
@found\_folder \<\< sub\_folder\_name  
@chat\_date \<\< f  
end  
else  
if sub.include?(“html”)  
path = File.join("/ACMServer\_exe/ChatHistory",f,sub\_folder\_name,sub)  
@file\_path \<\< path  
@found\_folder \<\< sub\_folder\_name  
@chat\_date \<\< f  
end  
end
