I need a module as like as File manager. We need to view, edit, modify and delete the files and also with permission option.
There are many modules available for managing files.
Reference URL : https://drupal.org/module-categories/file-management
Try this module : https://drupal.org/project/elfinder i think it suits your requirement.
I think the most robust file manager is Plupload. It does indeed have permissions that can be set. You can add functionality to it such as unzipping and selecting multiple files.
