Customize Zimbra Language file

[srandall@quadratek.net]

Hello

Would it be possible to customize the english language file and rename briefcase to File Store. We have a user base that we want to role out Zimbra to and they are not understanding Briefcase and dont like it. A simple change and then they will really embrace the change to Zimbra and use it.
Can anyone help? I have read the instructions on how to add a new translation, but am still unsure how to do that. I have tried editing the zhmsg.properties file but see no changes.

Many thanks
