C:\Users\<user>\AppData\Local\Digital_Matter_Embedded

Tip: (You can search your PC for the folder: "Digital_Matter_Embedded" )

Please note that the AppData folder is a hidden folder, so you would have to make sure hidden folders are being shown.  (see how to show hidden folders)

Please restart the sync application once this has been completed.
