When processing various files you notice a particular type of file gets collected but does not get processed. Due to no processing taking place, there's no processing action scheduled for the file type so logically there will not be an error message.
For some file types or MIME types, they are not assigned in the processing rules.
- The default processing rules handle many file types but are not configured to handle all possible file types.
- If you have a file type that gets collected but does not get processed you must configure the processing rules to process the file type.
- This can be done either based on MIME type or based on file extension.
As an example, take a Microsoft OneNote file:
- First add the extension .one to the custom extensions.
- Next assign a processor to handle the file.
- In the case of OneNote, adding the "Field appender (Default)" processor will ensure that this file type will be indexed and will show up in legal review.
