mise a jour indesign 2023

Hi @Emmanuelle280099628yuy 

Enable file extensions:

• In the search box on the taskbar, type file explorer, and in the search results, select File Explorer.

• In File Explorer under View, in the Show/hide group, select the File name extensions check box.

Then change the default application for the .indd file type.

• Right-click the file and choose Open With > Choose Another App>Select InDesign.
