Version control is based solely on the file name of the document being uploaded. When you add a new document with the same name as a previously added document, the count for the new document becomes 2 of 2 and the earlier version is 1 of 2. The count is based on how many other documents with the same file name are in the Document Bank when the current file uploads. When you add another document of the same name, the count for the new document is 3 of 3.
In addition, Lawtrac adds a number to the end of the file name for each file of the same name. For example, the following image of the Document Bank shows an example of multiple versions of the watermelon.jpg file.
