j ai sauvegarder mais je ne trouve pas le fichier
Which version / app of GeoGebra are you using, and on which device/OS?
Did you save your file locally (on your device: computer, tablet, phone) or online on your Profile page of the Materials platform?
I cannot see any material there: this means that if you saved your file online, it has been set as Shared with link or Private.
Ensure you've logged in with your GeoGebra account to see all your online materials.
