# Offline Sync ExpanDrive supports the ability to perform an offline sync of any mounted drive. This gives you the freedom to work with files from your connections, even when your device isn't connected to the internet. ## Overview of Offline Sync For Offline Sync, ExpanDrive must be running on your computer. With the remote service connected, you can download files or folders from your connections to your local machine while you're connected to the internet. After you disconnect from the network, you can continue to make changes to those downloaded items as long as ExpanDrive is still running. When you reconnect to the network, your changes are automatically synchronized to your remote storage. ## Using Offline Sync with Windows To enable Offline Sync, browse to the content that you would like to be synced, right-click the file/folder (you can select multiple items), and click Offline sync -> Local. ![Context menu in Windows Explorer](https://1753538908-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-M1WQstUIV0CAuN58yGb%2F-M1WSZOuiSxkEQ9H1dbU%2F-M1WTHBMFDJ4QAcqaqje%2Fimage.png?alt=media\&token=23ce2627-6dbc-44d9-bbf3-6e1a7b04a8ef) By default, all the items mounted on ExpanDrive are Online Only, which requires an active connection to the remote service. Editing files and folders that are Online Only changes them directly within your remote connections in real-time. To prepare for working offline, change the *Offline Sync* mode for the items to *Local.* ExpanDrive downloads the selected *Local* content to your computer. An internet connection is not required while you are working on *Local* content, but your ExpanDrive application must be running, and the connection must be in the "*Connected*" state. Any changes you make to *Local* data while offline will be synced when your computer is reconnected to the internet. ## Using Offline Sync with MacOS ExpanDrive must be running on your system in order to use Offline Sync. To prepare for working offline, use the *Download Now* option in Finder to store a local copy of the folder or file on your computer. An internet connection is not required to make changes in a folder that you've downloaded items in, but your ExpanDrive must be running. You can change or remove any of the downloaded files using Finder. When you connect to the internet again, changes you made while offline are synced to the remote system automatically. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
