Take a deep breath.
For something like this, we’re going to need a lot more information before folks can start to help.
- What’s your OS? (e.g. macOS 13.4)
- What version of Obsidian are you using (Settings > About in Obsidian)
- Where did you keep your vault? (e.g. in Documents? on the Desktop?) Can you remember? If not, in Obsidian’s vault switcher, the path (location) of your vault will be shown next to the vault(s) name.
- Do you have/keep backups of your main drive where the vault is?
- Do you use any sync services (e.g. Google Drive, iCloud, etc., where your vault might be?)
That can hopefully get us started.
