# Enrolling Files

Before Rockhopper can track changes to a spreadsheet, you need to **enroll** it. Enrollment connects the file to Rockhopper and creates the first version automatically.

## How to enroll a file

1. From the **My Files** page, click the **File Manager** button (top right)

![File Manager button on the My Files page](/files/JL6rdfhrr5CKDb2FA4T6)

2. A side panel opens showing the spreadsheets you have access to in OneDrive, SharePoint, or Google Drive
3. Select the files you want to enroll
4. Click **Enroll file(s)**

Rockhopper takes a snapshot of each file and creates an initial version. From this point forward, every change is tracked.

{% hint style="info" %}
If a file has already been enrolled by a teammate but isn't showing on your My Files page, click the **+** icon next to the file name in the File Manager to add it to your view.
{% endhint %}

## The File Versions page

Click on any file from My Files to open its **File Versions** page. This is where you manage the file's lifecycle.

The version list shows every committed version with:

* **Version number** (e.g. v1.0.0, v1.1.0) and who created it
* **Description** — the note written when the version was committed
* **Timestamp** — when the version was created, displayed in your timezone
* **Status** — whether the version is current, discarded, or reverted

From this page you can:

* Click any version row to open the [difference analysis view](/product-guide/tracking-changes.md#the-difference-analysis-view)
* **Download** any version as a file (click the download icon on the row)
* **Open the live file** in Excel or Google Sheets
* Access the [Comments](/product-guide/comments.md) and [Reviews](/product-guide/reviews.md) panels via the navigation bar
* [Create a new version](/product-guide/versions.md#creating-a-version), [discard changes](/product-guide/versions.md#discarding-changes), or [revert](/product-guide/versions.md#reverting-to-a-previous-version)
* [Pause or unpause edits](/product-guide/versions.md#if-other-users-are-working-on-the-file) when you need exclusive access
