Hello Mupositori Emmanuel,
folder sync is normally used by applications such as <a href=”http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=9e641c34-6f7f-404d-a04b-dc09f8141141″>Microsot ActiveSync</a> or, if you work within an organization, with Microsoft Exchange.
What is the exact error you receive with sync?
