> When *IdentifyMimeType* is presented with a text file with a `.csv` extension and the first two characters of the content as `P2`, the processor mis-identifies the mime.extension as `pgm` and mime.type as `image/x-portable-graymap`.
> The processor's *Use Filename In Detection* property is set to `true`.
> An example file is attached and the following flow and be used to reproduce: *GetFile* > *IdentifyMimeType* where the outputted flowfile's attributes can be inspected.
> This has been tested on NiFi versions `1.15.2` and `1.19.1` both running on a Window's Server 2019 instance.
