Checking Out and Checking In Documents
Checking out a document downloads a copy of the document to your working directory, and also locks the document so that no other user can check out or export the document until you check it in or free it.
When you finish editing a checked out document, you can check it in from the editing application as you are closing the document, or you can check it in later from ProjectWise Explorer. If your editing application is integrated with ProjectWise Explorer, you can update your changes to the server from the editing application without closing or checking in the document. This lets other users who have the same document copied out as a reference periodically refresh their copy of the document and see your updates.
To check out a document, the document must have a Checked In status, and you must have Read, File Read, and File Write privileges for that document. When you check out a document, the document's icon changes to a check mark for you, and other users will see a lock icon.
