App development often requires seamless interaction with tools like Github for branching, merging, and collaboration. Extend's Local Disk Sync feature bridges the gap between the Developer Site and other tools by providing local disk operations and 2-way file syncing.

Local disk operations:

-   Open from local disk: You can load apps or orchestrations from any locally stored directory, including those pulled from a Github repository or downloaded from App Hub, into App Builder or Orchestration Builder.
-   Save to local disk: All app files and assets are automatically saved to a designated local folder on your machine as modifications are made in the browser.
-   Edit on local disk: You can edit files in an Extend builder tool with the same experience as the cloud version, while working directly against your local copy.


2-way file syncing:

-   Changes you make within the App Builder or Orchestration Builder interface are automatically saved to the local disk.
-   Conversely, changes made directly in your local file system are immediately reflected in the builder tool's UI.


Note that Local Disk Sync works only with Chrome or Chromium-based browsers, and doesn't work offline.

To use Local Disk Sync, follow these steps:

1.  Create your Extend or Integration app and save it to App Hub. Your app must exist in App Hub before you can work locally.
2.  On the app's home page, select <b>Download Source</b> from the 3 dots menu. A ZIP file of the app's contents is saved in your browser's default download directory.
3.  Extract the contents of the ZIP file to the folder of your choosing.
4.  On the Workday Developer Site home page, from the <b>Build an Extend App</b> or <b>Build an Integration App</b> menu, select <b>Open a Local Folder</b>.
5.  Select the folder you extracted from the source download.
6.  Your app opens in App Builder. Note the Local Folder icon and text beside the app's name at the top of the UI, which indicates that your modifications are being saved locally. You can save your app to App Hub at any time, synchronizing your local version with the online version.


<b>Note:</b> To deploy a version of app to a tenant, you must save it to App Hub first.
