# When a computer is off

> A computer that is switched off, asleep or offline cannot be searched. Here is what to check.

TiDani keeps your files on the computer that holds them, so a computer has to be on and online for its files to be searched. If a file you expect is missing from answers, this is the first thing to check.

## Checklist

1. **Is the computer on and connected to the internet?** Asleep or offline counts as off.
2. **Is TiDani running?** By default it keeps sharing after you close its window. This depends on the setting **Keep sharing when TiDani closes** in Settings.
3. **Is the computer listed as sharing?** Open **Workspace**, then **Computers**. A computer that is offline is marked, and an admin can restart it.
4. **Was the file added recently?** New files are read on their own, but a big folder can take a few minutes. Use **Read changed files now** under **This computer**.
5. **Can you read it?** If the file is above your [access level](/docs/access-levels), TiDani leaves it out.

## If you are offline

The app shows "You're offline" and reconnects when your internet is back.

## Tip for teams

If important files live on one computer, ask its owner to leave it on during working hours, or share the same files from a computer that is usually on.
