Hello,

I open this thread for anyone who needs specific file extensions allowed for sharing in chatflows.

In our case, we need the “.bc3” extension, which is the standard data-transfer format for construction measurements in Spain. More info of FIEBDC-3: [Asociación FIEBDC: Formato de Intercambio Estándar](https://www.fiebdc.es/fiebdc/). Basically it is just plain text with the data (something like a csv).

Thank you in advance,

Regards

SVG and WebP would be nice.

Given we are a CAD company using HubSpot to support our customers, it’s a real pain not being able to support file types our products use. We need all Autodesk and general CAD industry file formats supported. Having to ask our customers to zip up files, when they are effectively already in a proprietary zip format creates friction in the support flow. It’s a real shame admins can’t allow additional file extensions.
