Parts Tracker allows you use a local wired network to access the database from multiple computers at the same site.
Important: You should not use file sharing over wireless local networks (Wifi) or wide area networks (e.g. VPN over Internet) because of slow speeds and the risk of drop outs causing data file corruption. See the article below for alternatives for remote access.
For instructions and limitations please see this article: How to share the data file across a network.
