The Microsoft Upload Centre gives you a way to see the state of files you are uploading to a server, in once central location. When you upload a file to a web server, Microsoft first saves the file locally to the Office Document Cache, before it starts the upload.
This is useful if:
You have opened a file from a server, and the server goes offline. You can save the file, knowing that it will be uploaded when the server goes back online.
In situations where you need to save files to your server prior to disconnecting, you can check the status by checking the Upload Centre. You will be able to tell when the upload has completed and you can disconnect.
An error occurs during the upload. You are alerted immediately, so that you can fix the problem and resume the upload quickly.
The Microsoft Upload Centre handles Synchronization of Documents back to SharePoint (and Breeze) and any conflicts that may occur.
If a conflict occurs (during upload), the Upload Centre will notify you of the conflict. The following steps may help to resolve the issue:
1) Click the Upload Centre icon in the notification area and click Open Upload Centre.
2) Locate the file in which the conflict occurs and click Actions or Resolve adjacent to the file, and then select what you want to do from the menu.
3) You can also select the file that you want to work with and access file actions through the Actions menu in the toolbar, and through the context menu for each file. The available options will change depending on the state of the file:
- Choose - When an upload has failed because another author has changed the server version of the file causing a conflict, this action opens a window where you can view and select which version to keep.
- Open - Opens the file so that you can view or edit it directly from the Upload Center.
- Open to Resolve - When an upload has failed you can open the authoring application that will automatically display more information about the issue and actions to resolve it. This action is often the default action to resolve upload failures.
- Open Web Site - Opens the web site where the file is saved.
- Save As - Saves a copy of the file to your computer.
- Save a Copy - This action resolves an upload failure by saving your changes to another location.
- Sign In - When an upload has failed because you are not signed into the web server this action lets you sign to the resolve upload failure.
- Discard - Removes the file from the Upload Centre. If this file is on the server it will still be available for download.
- Upload - This action tries to upload your pending changes to the server.
Depending on the version of Office and therefore Office Upload Center you have, you may all have a slightly different experience.
