US Patent 8631346 File conversion initiated by renaming of file extension

Some embodiments of a system and a method to process file conversion initiated by natural human behavior have been presented. For instance, a file conversion manager running on a processing device may intercept an operation invoked by a user to rename at least a first extension of a file name of a file having an original file format to a second extension associated with a target file format. In response to the operation, the file conversion manager may select and execute one of a group of third party file conversion applications to convert the file from the original file format to the target file format.
