# File Versioning in Ontraccr

## **🕒 File Versioning in Ontraccr**  
 

Ontraccr automatically tracks file changes by saving new versions — whether you annotate a document or upload an updated file. This helps teams stay aligned and ensures that previous versions are always accessible.

* * *

## **🔁 What Triggers a New Version?**

New versions are created in two ways:

### 1\. **Annotating a File**

-   When you open a file and make annotations (in either the Basic or Advanced Viewer), clicking **Save** creates a new version
-   The annotated version is stored on top of the original, but you can still access earlier versions

### 2\. **Uploading a File with the Same Name**

-   If you upload a new file with the **exact same name** as an existing one, Ontraccr will detect the match
-   The system automatically treats it as a **new version** of the existing file, not a separate document

## **🗂 Viewing File Versions**

To see all versions of a file:

1.  Click the **More** icon (three vertical dots) next to the file
2.  Select **Versions**
3.  You’ll see a list of all saved versions, including:
    -   Timestamps
    -   Who created or uploaded the version

You can click any previous version to:

-   View it
-   Download it

💡 Tip: Only the most recent version is shown by default — especially on the mobile app.

## **📱 Mobile vs Web Behaviour**

-   **Mobile App**: Always displays the most recent version of a file
-   **Web App**: Allows you to choose and view older versions if needed

## **🏗 Use Case: Construction Drawings**

Versioning is especially helpful for workflows like construction drawings:

-   Teams often revise drawings during a project’s lifecycle
-   Instead of deleting or overwriting, you can upload updated plans using the same file name
-   The system keeps all previous versions so nothing gets lost

📌 Example: If you upload “LightingPlan.pdf” multiple times, each update becomes a new version. The original file is preserved, and users can always go back and compare.

## 🧾 **Summary**

-   Annotating or re-uploading files (with the same name) creates new versions automatically
-   You can view, download, or revert to older versions from the **Versions** section
-   Web users can access past versions; mobile users see only the latest
-   Versioning helps ensure everyone is working from the latest documents — without losing history
