Do you know, that… ?
Having an assembly, you can save all of its component files to a neutral format (open) typu *.STEP lub *.IGS. Of course, I don't mean that, that you have to open each file and select save as… Yes, it is also possible if there are several files, if there are several dozen or more of them, this method becomes troublesome.
Meet my solution.
To bulk save files to one of these formats, you can use task scheduler available from the SW Professional package.
In the schedule you must select Export files specifying a folder, in which the assembly and component files are saved.
Another option, but only available for the format IGS saves the assembly as * .igs with the option unchecked Save all assembly components in one file.
