Container of files paths names

Get

obj[index].path: return the full path to the file

obj[index].folder: return the folder of the file

Get

obj[index].file_name: return the file name

Get

obj[index].extension: return the file extension

Get

obj[index].file_name_noExt: return file name without extension basename

Get

obj[index].path_noExt: return path without extension

• Paths are indexed as a list so it can be use as a list

• Use obj[index].property or obj[index].function
