• fileExists(file_path)
• folderExists(folder_path)
• readFile(file_path[, options])
• readJSON(file_path[,options])
• delFile(file_path)
• writeFile(file_path, data[, options])
• getModulePackInfo([module])

if data is neither Buffer nor String, JSON.stringify will be applied with extra two optional params in options,[replacer][space]

• delFolder(folder_path[,force])

YOU KNOW WHAT YOU ARE DOING !!!!! forcely to delete all files in this folder recursively.

• addFolder(folder_path)
