# Working With Files

Codex works best when the folder is local on your computer.

## Good Practice Folder

Use a folder you can safely change, such as:

```text
~/codex-work
```

Avoid using an important work folder for your first experiments.

## OneDrive And SharePoint

OneDrive and SharePoint can be useful for ordinary files, but sync tools can cause confusion when files change quickly.

For first practice:

- copy sample files into a local practice folder
- avoid real student or participant data
- keep tokens and private screenshots elsewhere
- ask Codex to explain before moving or renaming many files

## Git

Git records changes over time. It is useful later, but not required for the first activities.

If Codex mentions git, ask it to explain what it is doing before it runs commands.
