| Typically, an Omnidex Environment is a directory with subdirectories that contain all of these elements. This is often the most convenient approach since whole directories are easy to move and back up. In many cases, however, the database and indexes are large enough that they must span multiple disk drives or even machines.

| Omnidex Environment Files also serve an important role in connections. An [[dev:connections:home|Omnidex Connection String]] points to an Omnidex Environment File. This means that the Omnidex Environment File is the starting point for nearly every Omnidex operation. | Omnidex Environment Files also serve an important role in connections.
