If two people change the same file at the same time, Dropbox won't try to merge the changes. Instead, it will save the original file as well as a second version which has the same name but is appended with "conflicted copy," the name of the person or computer responsible, and the date the conflict occurred. By creating a conflicted file, Dropbox ensures that all changes are preserved and nobody will overwrite another person's hard work.
Conflicted copies can also occur when a file is left open on another computer, especially when using applications with an auto-save feature. Closing the file from within the application on either computer should prevent further conflicts.Category: Sharing
