How did datatypes work?

[sim085]

Hello, Is there a good explanation of how data types worked? Also was this the default way how files where handled/opened on workbench?

Yes, but is there any documentation of how this worked internally and how I might develop a new datatype?

First of all thank you very much for your help.

You should be more specific in your questions then. There most certainly is.

Sorry for not being specific. What I am looking for is an explanation of how datatypes work. For example what happens when the user clicks on a file? How does the system know which datatype is responsable for which file? Does it loop through every installed datatype and each datatype opens the file (or part of the file) to determine if it is responsable for it?

I am not an experianced amiga user and therefore do not know where to look for this information. I will see the code of that datatype but not sure if I'll be able to understand it.

Thanks again.
