The “Exchange all files” process is similar to a round of Send/Receive being done by all users in the session.
The first user does a commit (saving all changes made locally to history - like a “Mark point in project history”) and then a file with all the changes is sent to other users in the session.
When another user receives the file, local changes will be saved and the received file will be merged with the local changes. This may cause this user to send another file with changes.
The process continues until all users are up to date with the same new version. There is locking while all this is happening, so users have to do this process one at a time.
The main reason for “Exchange all files” is that a PTLive session only sends changes made in the Scripture text during the normal processing of a session.
