A generalized data import mechanism we call Data Connectors was added in Origin 2019b. As the name implies, Data Connectors create a live link between your project and an external data source -- either a local file or web-stored data.
By default, when import data size exceeds 500kB, imported data and graphs made from that data, are NOT saved with the project file. Thus, if you have connected to a large data file and have not changed the value of LabTalk system variable @DNS (see below), you will open your project file to see that your imported data and any graphs made directly from that data, are missing.
