There are three possible reasons you might want to log out of the iFolder server:
The Logout feature allows users to share an identity for accessing an iFolder account and to timeshare the same files. Because iFolder does not provide a file locking mechanism to enable file sharing, you cannot have multiple users simultaneously logged in to a single iFolder account from different workstations, using the same files collaboratively.
The Logout feature allows you to log out of your current iFolder session, because a user cannot be logged in to more than one account at the same time on the iFolder server.
To log out of your current iFolder client session, right-click the iFolder icon, then click Logout. Even though you are logged out, the iFolder client is still tracking changes between the files in your working folder and the iFolder server.
