If you are working with Dimensions Streams, you can lock files to prevent other users from delivering changes while you are working the files. This is particularly useful for file types that cannot be easily merged, such as binary graphics files.
To lock files:
In Eclipse, right-click the files and select Team | Lock. The Lock dialog box appears with the list of files to lock. You can optionally de-select files to lock from here.
Click Finish. The locked files appear with a padlock icon. Note that any files with brown padlock icons are currently locked by other users.
To unlock files:
In Eclipse, right-click the files and select Team | Unlock. The Unlock dialog box appears with the list of files to unlock. You can optionally de-select files to unlock from here.
Flick Finish.
