Sooner or later you may face the problem of how to change the names of a large group of files. A case in point is a situation wherein you have a group of files – perhaps a group of episodes from a TV series that have been named correctly, but in a non-standard format – and you need to change those file names to conform with an accepted standard, for example, in the form of SXXEYY where XX is the season number and YY is the episode number, followed by the file type suffix. This code is often referred to as the “Sexxyy” standard.
The original files may come from a variety of sources, many of them ad hoc and without regard for the standards, or perhaps named for a different standard (there are several to choose from).
