Export your exported project file as a `.export` and save it to the repository folder. Once you perform the appropriate [commit and push](/docs/git-based-source-control/basic/making-changes/saving-changes.md#commit--push-a-change) operations, you'll be able to see your project file and all of its data from both the Web App and Desktop App.

### Graphical Display and Differences

#### General

When the exported project file is selected in the Web App or Desktop App, Copia displays the project tree structure in a way that's familiar to users of CODESYS based software. This way, you can easily navigate to a project item or identify differences.
