Here is the procedure to manually copy projects from one PC to another: Make hidden items visible (on Windows 10, in File Explorer > View > Check Hidden Items). Identify the Users folder. In the case of the portable application, go to the folder of the portable version and then to BDNF_Data > BDNFProjects > Users In the case of the installed version, go to C: > Users > username > AppData > LocalLow > BNF > BDNF > BDNFProjects > Users Copy the user's folder (for the user Antoine, I copy the folder Antoine which is in the Users folder). Send the folder to the second PC. Add the folder in the Users folder of the second PC (use the path from point 2.). Translated with www.DeepL.com/Translator (free version)
