File extension ID or identification process refers to identifying what kind of information is located in a file with unknown or scrambled extension. Also there are lots of files with extensions which don’t really describe what kind of information is stored in the file. Examples of such extensions are DAT and BIN. To get understanding of what kind of information is stored in a certain file you need to use software like HEX editor or other kind of investigation techniques described in this site.
If you think you know software from which file originated you can try renaming file in question to have extension which is produced by that software and then try opening it. This may solve the issue.
Alternatively File extension ID=0413 could refer to file with extension ID. Files with extension ID could contain following information:
