Checking Out and Checking In Files to Briefcase
You can open files in your Briefcase any time you log on to your account. You must have the appropriate software application to open and read or updated files that you did not create with the documents tools in Briefcase.
If you have shared a briefcase with others, you may want to use the check-out and check-in feature of Briefcase to manage editing of files. The check out and check in process is slightly different depending on whether the file is one you uploaded to your briefcase or a documented in created in briefcase
Go to the Briefcase tab and select the file that you want to check out.
Click Actions>Check Out File.
In the dialog that displays, select to save the file to your computer. Because you checked out the file, you must save it to your computer to edit it, as the file has been marked as read-only and changes to the file cannot be saved.
Edit the file with the appropriate tool and save it.
After you saved the file to your computer, right-click on the locked file from the Briefcase file list and select Check In File.
In the Check In File to Briefcase dialog that opens, browse to the edited file on your computer. If you want to add information about changes, enter this is the Notes text area.
Click Check In. The file is uploaded. The lock is removed and the file details, including a new version number and notes, are updated in the file list.
