Different input shapes in the same model

Hey guys,
I have a problem and I would appreciate your help.
I want to create a model that takes a folder full of files of various types and categorizes by given categories based on content, the problem is that each file type has different features architecture and input shapes if I want it based on content, there is always the option to create a different model for each file type, but I was wondering if it can be done with a single model.

Any ideas would be highly appreciated!

I do not think so. Models tend to rely on all of the examples having the same number of features.

Pre-processing can be used in some instances, for example to re-size images into a common shape. But that would not allow a model to handle both images and tables of data, for example.
