Detect bundles

[kieranjol]

Hi, I've encountered some Bundles: https://en.wikipedia.org/wiki/Bundle_(macOS), particularly https://en.wikipedia.org/wiki/Rich_Text_Format_Directory and I was wondering if Brunnhilde could report on their existence? Attached is a zip that contains an RTFD. On Windows it just appears as a folder with an rtf and a jpg, but on Mac, it appears as a single file and opens in TextEdit with the jpeg embedded in the correct place in the RTF. Another example is Mac .app folders.

As Siegfried (pinging @richardlehane in case this is more relevant to Siegfried ) and PRONOM are file-based, I wonder if Brunnhilde could detect bundles (folders with 'file extensions') and include them in the HTML report for further investigation? It would be great to bring these files to the attention of Windows users (and maybe even Mac users) who may not know that they're dealing with a complex object.
I could look into helping with this if it seems like a useful inclusion?

hi @kieranjol - I think I agree, this is probably better suited for a level above siegfried which, as you note, is focused on files!

Thank you so much Richard!

I have been working on this from the MacOS side. You can see a draft python script here. I will also be presenting on this topic at iPres in NZ. I am sure we can find a way to have tools like Brunnhilde use tools like this to get better format information.
