fichiers introuvables

Bonjour, Lucien - (and that's the extent of my French...)

From the screenshots, it appears that you are using OneDrive to either store (archive) your Storyline files, or that you are trying to actively work on your Storyline files. It may also be that you are looking for the published story file to view in HTML. I am not sure which is the case.

If you have archived your Storyline files on OneDrive, and now you cannot locate those files, that is a problem with how your OneDrive settings are configured. Depending on whether your OneDrive settings are controlled by your organization, an IT department, or you, that would be a question to work out with that organization or department. (In our company, for example, some OneDrive files [usually videos] are deleted after 12 months.)

If you are trying to work on your Storyline files from the OneDrive location, it is not surprising that you are having issues. Storyline works from a local drive only:

C\YourComputerName\Documents\My Articulate Projects

It is possible to keep an archive or backup copy of a story file on OneDrive, but working on it directly from that location is not likely to give good results. And based on the second image, I would not even publish to a OneDrive location; you may have all sorts of issues. It is better to publish to a local drive (for example: C\Temp) and then copy the output over to the OneDrive location.

If the problem is that you are looking for the story.HTML file (in my screenshot), and you do not see it in the published output location, I would try republishing (from the *.story file on a local drive, to a local drive output) and see if that fixes the problem. If it does not, I suggest that you contact Articulate support directly.
