See our quick summary about checking-in and out your content for WebDAV.
Details
Web composition packages like Dreamweaver and GoLive contain the concepts of Workgroup Support and Checking files In and Out. This allows shared publishers to avoid conflicts with each other when updating files. For more information consult the Help in your web composition package.
Checking Out a file has the effect of locking the file on the WebDAV server. This means that you must Check In the file when you have finished updating it, to remove the lock.
