# Windows network share

> Synchronize files from a Windows network share to SharePoint so they can be used in Prophecy

Organizations often store source data on Windows network shares or mapped drives.

Because these file shares are not directly accessible from cloud-native applications, Prophecy recommends synchronizing them to Microsoft SharePoint Online and then [connecting Prophecy to SharePoint](/data-analysis/environment/connections/sharepoint).

## How it works

Instead of connecting Prophecy directly to a Windows network share, use SharePoint Online as an intermediary.

This approach allows you to continue managing files on your network while making them available through a supported cloud connection.

## Synchronize your network share

Prophecy does not synchronize files between a network share and SharePoint. Instead, you should use a Microsoft-supported migration or synchronization tool to keep your SharePoint document library up to date.

Microsoft recommends using one-way incremental synchronization, where changes made on the network share are periodically copied to SharePoint. This approach minimizes synchronization time while avoiding conflicts that can occur with two-way synchronization.

Common Microsoft options include:

* **[SharePoint Migration Tool (SPMT)](https://learn.microsoft.com/en-us/sharepointmigration/introducing-the-sharepoint-migration-tool)** for standalone or scripted migrations.
* **\[SharePoint's Migration Manager]\([https://learn.microsoft.com/en-us/sharepointmigration/mm-get-started](https://learn.microsoft.com/en-us/sharepointmigration/mm-get-started)** for centralized enterprise deployments.
  For implementation details, refer to the [Microsoft SharePoint migration documentation](https://learn.microsoft.com/en-us/sharepointmigration/introducing-the-sharepoint-migration-tool).

## Connect Prophecy to SharePoint

After your files are synchronized to SharePoint Online, [create a SharePoint connection in Prophecy](/data-analysis/environment/connections/sharepoint) that includes:

* Your SharePoint site URL.
* Your Azure Active Directory tenant ID.
* Your Azure application (client) ID.
* Your Azure client secret stored as a Prophecy secret.

For the required connection properties, see the [Microsoft SharePoint connection properties API](https://learn.microsoft.com/en-us/sharepoint/dev/spfx/connect-to-sharepoint).

## Best practices

* Use one-way incremental synchronization instead of two-way synchronization.
* Schedule synchronization based on how frequently your source data changes.
* Treat SharePoint as the data source that Prophecy reads.
* After migration is complete, consider transitioning users to work directly from SharePoint rather than the original network share.
