I am trying to create a drupal file control system.
File field using some of the other contributed modules looks like a good way to build the system...however...
I am unsure how file field handles revisions of a file.
When the node is edited and a file in a file field replaced can you still access the older file? And how is this indicated as an older file?
Is file field secure enough to ensure sensitive business documentation will not be publicly available?
If this is not the case then is there some system that can provide all of the requirements of a document control system?
