Sync Folders Mac

Find out how to use the EWS Managed API or EWS to get a list of folders, or a list of folders that have changed, in order to synchronize your client.

• SyncFolders helps you to synchronize the contents of two folders, including any subfolders. The folders may be on different disk drives, on the network, or storage devices attached to the USB port, including external hard disk drives, flash drives, and any other type of USB storage device. The program allows you to easily copy new and updated files and folders in either or both directions.
• Simply select the “Synchronize” option from the top navigation menu, select a primary folder and secondary folder under Sync Folders section and click on the button “Analyse.” Once you are happy with how sync works, click on the “Sync” button to commit and perform the synchronization.

EWS in Exchange uses item synchronization and folder synchronization to sync mailbox content between the client and server. Folder synchronization gets the initial list of folders from a root folder and then, over time, gets changes that were made to those folders and gets new folders as well.

If you're performing folder synchronization by using the EWS Managed API, you first get the initial list of folders in the root folder by using the ExchangeService.SyncFolderHierarchy method. You then update the value of the cSyncState parameter during subsequent calls to get the list of new and changed folders.

To perform folder synchronization by using EWS, you request the initial list of folders in the root folder by using the SyncFolderHierarchy operation, parse the response, and then at some point in the future get the changes to the folders in the root, and parse the response. After the client receives the list of initial or changed folders, it makes updates locally. How and when you retrieve changes in the future depends on the synchronization design pattern your application is using.

Sync Files to Your PC on a Local Network with SyncToy (Windows only, but can sync to any shared folder) Free Windows utility SyncToy is a simple tool that synchronizes files between two folders. Sync the files in your Microsoft 365 or Microsoft SharePoint site libraries so they’re always available on your computer, even when you’re offline. Turn on Files On-Demand in OneDrive In the Windows notification area, select the blue OneDrive cloud icon.

The following code example shows how to get an initial list of folders in a root folder and then get a list of changes to folders in the root folder that have occurred since the previous synchronization. During the initial call to the ExchangeService.SyncFolderHierarchy method, set the cSyncState value to null. When the method completes, save the cSyncState value locally to use in the next SyncFolderHierarchy method call. In both the initial call and the subsequent calls, the folders are retrieved in batches of ten, by using successive calls to the SyncFolderHierarchy method, until no more changes remain. This example sets the propertySet parameter to IdOnly to reduce calls to the Exchange database, which is a synchronization best practice. In this example, we assume that service is a valid ExchangeService object binding and that cSyncState represents the sync state that was returned by a prior call to SyncFolderHierarchy.

After you retrieve the list of new or changed folders on the server, create or update the folders on the client.

Get the initial list of folders by using EWS

The following example shows an XML request to get the initial folder hierarchy by using the SyncFolderHierarchy operation. This is also the XML request that the EWS Managed API sends when retrieving the list of initial folders by using the SyncFolderHierarchy method. The SyncState element of the SyncFolderHierarchy operation is not included because this is the initial synchronization. This example sets the BaseShape element to IdOnly to reduce calls to the Exchange database, which is a synchronization best practice.

The following example shows the XML response that is returned by the server after it processes the SyncFolderHierarchy operation request. The initial response includes Create elements for all folders because all folders are considered new during an initial synchronization. The values of some attributes and elements have been shortened for readability, and some Create element blocks were removed for brevity.

After you retrieve the list of new folders on the server, create the folders on the client.

Get the changes since the last sync by using EWS

The following example shows the XML request to get the list of changes to folders in the root folder by using the SyncFolderHierarchy operation. This is also the XML request that the EWS Managed API sends when retrieving the list of changes to the root folder. This example sets the SyncState element value to the value returned in the previous response. And for demonstration purposes, this example sets the BaseShape element to AllProperties instead of IdOnly to show the additional properties returned. Setting the BaseShape element to IdOnly is a synchronization best practice. The value of SyncState has been shortened for readability.

The following example shows the XML response that is returned by the server after it processes the SyncFolderHierarchy operation request from the client. This response indicates that one folder was updated, one folder was created, and one folder was deleted since the prior synchronization. The value of the SyncState element, Id attributes, and ChangeKey attributes have been shortened for readability.

Remember that the request included the AllPropertiesBaseShape. This is just for demonstration purposes. We recommend that you set the BaseShape element to IdOnly in production.

Update the client

If you're using the EWS Managed API, after you get the list of new or changed folders, use the Folder.Load method to get properties on the new or changed items, compare the properties to the local values, and update or create the folders on the client.

If you're using EWS, use the GetFolder operation to get properties on the new or changed folders and update or create the folders on the client.
