Hi all, I am new to root and wanted to ask basic question of accessing the root files. I would like to loop over the folders and then opening each folder and then open the root file inside these folders. Also, I am using root version 6.2. So I am using TSystemDirectory for looping over the folders …

[samoz] How can I get the list of files in a directory using C or C++? c++, c, file, directory asked by samoz on 07:35PM - 04 Mar 09 UTC inside the loop you can do f = TFile(*iter) RK

Dear RK, I can’t able to get your comment. Can you explain little more? I can already get the list of files from the above code but I want to open each of these folders and get the root file.
