This is possible as the scribe files are actually saved in an XML format on your computer (base folder). However we wouldn't recommend editing through this method as you could corrupt your scribe, lose data and cause issues within the application. We can also not guarantee to be able to support you with issues you may cause if editing your files that way. If you decide to edit in this way I would back-up your work before hand just in case.
So if you decide to proceed how do you find the XML... C:\Users\[user.name]\AppData\Roaming\VideoScribeDesktop\Local Store\Documents is the base Library and the XML files are in the Zip folders. The scribes won't be named they will instead have a unique ID but the scribe name is in the first line of XML.
