If you are going to share an inventor file with another person that has an inventor installed, you should both work with the same version of inv, if they have different versions they should export and import in step format, but with this format you can not visualize the development of operations in the browser will only see imported solids if a part file is for example.
If you want to share with another person who does not have an inventor installed, you should also import it in step format. Other formats that are also commonly used in other programs are sat, x_t, iges and many others
I will be attentive to any questions you may have
