After you download, install, and sign in to ProjectWise Drive with your Bentley IMS account, you can then go back to ProjectWise Web and synchronize any work area connection that your administrator has enabled for use with ProjectWise Drive.
You can synchronize a work area connection by going to Settings > ProjectWise Drive options in ProjectWise Web.
Note: You must be signed in to the work area connection in ProjectWise Web using the same Bentley IMS account that you are signed in to ProjectWise Drive with.
In the ProjectWise Drive options dialog, turn on Synchronize this project (move the slider to the right) and click Save. The dialog will tell you which connection in the project will be synchronized.
Note: Technically speaking, you are synchronizing the entire project, and all work area connections in that project that are enabled for ProjectWise Drive will be synchronized with your computer. However, currently only one work area connection per project can be enabled for ProjectWise Drive, so when you synchronize a project, only one work area connection in that project (the one that is enabled for ProjectWise Drive) will be synchronized with your computer.
Once you synchronize the work area connection, it becomes available in the ProjectWise Drive node in File Explorer. Expand the work area to find the documents and folders you want to work on.
If you synchronize projects that belong to different organizations, you would see multiple ProjectWise Drive nodes in File Explorer – a node for each organization and under that node there will be the synchronized projects from that organization:
What documents will I see in ProjectWise Drive?
Only the documents and folders that you have access to in the work area in ProjectWise will appear in ProjectWise Drive. You will not see any folders or documents that you do not have access to. If a document has versions, only the active version of the document will appear in ProjectWise Drive (assuming you have access to the active version). Also, you will not see any documents in ProjectWise Drive that are not downloadable. For example, if you have Document Read permission (permission to see the document in the list) but not File Read permission (permission to open the file) on a document in ProjectWise, then you will not see that document in ProjectWise Drive. Also, a placeholder document (a document in ProjectWise that has no file attached) will never appear in ProjectWise Drive, since there is nothing to download.
Does synchronization download documents?
Synchronization alone does not download any documents, it just establishes links to the documents you have access to in ProjectWise. Documents are only downloaded when you explicitly download them, or as needed when you open or check out a document.
How much space will a synchronized work area take up?
You can open the properties of a work area in ProjectWise Drive to find out the total space that all the documents you have access to in the work area take up in ProjectWise (Size) and how much actual space that all the documents currently downloaded from the work area are taking up on your computer (Size on disk). You can also open the properties of a particular folder within the work area to find out how much space the documents in that folder and its subfolders take up.
Status icons
When you select a folder in the navigation pane on the left, the Status column in the document list on the right shows the status of the documents and folders in the selected folder. For example, if there is a cloud icon 
next to a document, it means that the document is available in ProjectWise, but there is no local copy of the document. The meanings of the various status icons are described in another section (Document and Folder Status Icons).
File location
While you only ever need to work from the ProjectWise Drive node in File Explorer, the actual location on your computer that ProjectWise Drive synchronizes projects to (and downloads files to) is:
C:\Users\<user.name>\ProjectWise\<organization>\<project name>\<parent folder>\<document folder>
Where <user.name> is the name of the user you are logged in to the computer as, <organization> is the name of the organization that owns the ProjectWise project, and <project name> is the name of the ProjectWise project.
Removing a project from ProjectWise Drive
If you no longer want a work area connection to appear in ProjectWise Drive, you can remove it by un-synchronizing the work area connection in ProjectWise Web.
Note: It is recommended that you first check in or free any documents that you have checked out before you un-synchronize a work area connection.
You can un-synchronize a work area connection by going to Settings > ProjectWise Drive options in ProjectWise Web.
In the ProjectWise Drive options dialog, turn off Synchronize this project (move the slider to the left) and click Save.
The work area connection is removed from the ProjectWise Drive node in File Explorer, and any downloaded documents (that are not currently checked out to you on this computer) are automatically deleted from the download location. Any downloaded documents that are still currently checked out to you on this computer, and any local files that you added to the work area in ProjectWise Drive but have not yet added to ProjectWise will remain in the download location.
Note: If you are not sure which ProjectWise project contains a particular work area connection, remember that you can just right-click the work area connection or any folder or document in ProjectWise Drive and select Open in ProjectWise Web. This opens a browser tab and takes you directly to the work area connection in ProjectWise Web.
