Adding Users in CSV Format
To add many users easily, a CSV (Comma-
Separated-Variables) file is recommended.
This is a text file, with each line consisting
of a Username, Password, and Description
separated by commas and ending with a
carriage return. These files can contain from
1 - 1000 users. Paste the contents of the CSV
file into the CSV input window and click on
Start Import.
The users from the CSV file will be added to the
list of local users for the TeraStation.
Note: Paste the contents of the CSV text file
into the CSV input window, not the text file
itself.
