Renamers are software applications that help users easily change the filename of one or, more frequently, multiple files.
These utilities will allow users to apply templates to their files, but they can also append suffixes or timestamps to the selected files, so that they can be sorted and organized easier.
File renaming can be performed manually, but when dozens of files are involved, these applications increase efficiency because they support batch modes.
File renamers can typically be used to manage a certain type of files, like graphic, multimedia or text files, but they can also be used to handle all file formats within a certain folder.
