Hi! New 3DExperience user here... I have a somewhat large assembly (a few dozen Catia files) that I pulled down from 3DExperience and saved to my desktop before making changes to many of the component parts (bad choice in retrospect, but at the time I wasn't sure that my design changes would become the real path forward. Now I want to upload my version of the assembly and its files, but when I try to do so, 3DExperience makes a new file for every file, rather than overwriting the corresponding old files that already exist in 3DExperience. I'd like to be able to upload my changes and overwrite the original files... how can I do so?
Thanks in advance!
