You can modify the category for a file or group of files to collectively enforce a defined set of behavior, rules, and properties for the selected vault objects.
Behavior for a particular category can be changed by an administrator in the Autodesk Vault stand-alone client.
Change a File's Category
Use the Change Category command to transfer a file or group of files from one category to another. When you change the category for a vault object, that object inherits the behaviors specified in the new category.
For example, a category called Engineering has a certain lifecycle definition assigned to it, and that lifecycle is configured to perform an automatic revision bump on files when a change state occurs. If a file is moved to the Engineering category and goes from the Work in Progress state to the Review state, the file will automatically undergo a revision bump based on its Category and the lifecycle definition assigned to it.
